Joining 3D printed parts shouldn’t be guesswork. In this video, we break down the most reliable ways to connect multi-part prints — without relying on perfect tolerances, support-heavy features, or fragile pegs. You’ll see why common connectors fail, and better options you can use instead, from diamond pegs and slab-and-slot joints to spring-loaded T-slots, snap fits, and advanced locking tabs. Whether you’re making terrain, models, or large assemblies, these design rules help your parts fit cleanly, hold tightly, and print reliably on any machine.
A federal judge in Missouri ordered supplemental briefing in Brown v. ATF, a case challenging the NFA’s registration scheme and regulation of suppressors and short-barreled rifles. IMG Jim Grant
A federal judge in Missouri has ordered additional briefing in a closely watched challenge to the National Firearms Act, signaling that the case raises serious unresolved questions about the government’s post-tax treatment of National Firearms Act (NFA) firearms, as well as the Second Amendment status of suppressors and short-barreled rifles.
In Brown v. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), Chief U.S. District Judge Stephen R. Clark of the Eastern District of Missouri issued an order on March 24, 2026, directing both sides to file supplemental briefs on several threshold and constitutional issues before the court moves further into the case.
The lawsuit was filed after Congress, through the One Big Beautiful Bill Act, reduced the NFA’s excise tax for most covered firearms to $0 while leaving the NFA’s registration regime in place. According to the order, the plaintiffs argue that Congress exceeded its enumerated powers by keeping the registration system intact after stripping away the tax that had long been used to justify the statute. The plaintiffs also argue that the NFA’s regulation of short-barreled rifles and suppressors violates the Second Amendment.
In addition to individual plaintiffs Chris Brown and Allen Mayville, the lawsuit includes Prime Protection STL, LLC, and a coalition of prominent gun-rights groups: the National Rifle Association, Firearms Policy Coalition, Second Amendment Foundation, and the American Suppressor Association. The defendants are the ATF, acting Director Daniel P. Driscoll, the Department of Justice, and Attorney General Pamela J. Bondi.
Judge Clark’s order makes clear that the court has not yet ruled on the merits. It does not strike down the NFA, enjoin enforcement, or hold that the plaintiffs are likely to prevail. What it does show is that the court believes the case presents several “novel issues” that require focused briefing before the litigation can advance.
Court Focuses First on Standing
The first issue the court wants answered is whether the plaintiffs have Article III standing to bring the case at all. Because this is a pre-enforcement challenge, the plaintiffs are not claiming they have already been prosecuted. Instead, they argue that they want to engage in conduct involving NFA-covered firearms without complying with the NFA, but are refraining because they fear federal enforcement.
Judge Clark noted that, in a pre-enforcement case, plaintiffs must show that the threatened enforcement is sufficiently imminent and that they intend to engage in conduct “arguably affected with a constitutional interest.” He specifically ordered the parties to address whether the plaintiffs’ claimed injury in Count I—the argument that Congress improperly exercised its enumerated powers—is tied to a personal constitutional interest or is instead a generalized grievance that federal courts cannot hear.
That question could be important. If the court finds the plaintiffs lack standing on that part of the case, it could narrow the dispute even if the broader Second Amendment claims remain alive.
Judge Orders Briefing on “Common Use” and “Dangerous and Unusual”
The court also wants more briefing on how modern Second Amendment doctrine applies to the NFA’s regulation of short-barreled rifles and suppressors.
Citing District of Columbia v. Heller and New York State Rifle & Pistol Association v. Bruen, Judge Clark laid out the familiar framework: when the Second Amendment’s plain text covers the conduct, the Constitution presumptively protects it, and the government must then justify its regulation by showing it is consistent with the nation’s historical tradition of firearm regulation.
But the court wants the parties to dig deeper into one of the most disputed questions in post-Bruen gun litigation—what exactly Heller’s “common use for a lawful purpose” language means.
Judge Clark ordered briefing on whether “common use” is mainly a statistical inquiry, meaning how widespread a firearm or item is among law-abiding Americans, or whether it is better understood as part of the inquiry into whether a weapon is “dangerous and unusual.” He also wants the parties to address whether the “common use” inquiry belongs at Bruen’s first step or second step, and who bears the burden at the first step.
Those are not small questions. How the court answers them could affect how lower courts analyze not just SBR restrictions, but other modern arms-related challenges as well.
Suppressors Get Their Own Threshold Question
One of the most notable portions of the order deals specifically with suppressors. Judge Clark directed the parties to address whether suppressors are actually “Arms” under the original public meaning of the Second Amendment. In doing so, the order cites several cases describing silencers as accessories rather than weapons in themselves.
That does not mean the court has adopted that view, but it shows that the suppressor portion of the case may turn first on a threshold definitional question before the court ever reaches historical analogues or broader constitutional balancing.
For gun-rights advocates, that issue is critical because suppressor litigation has increasingly focused on whether these devices should be treated as protected arms, protected components of arms, or merely regulated accessories outside the Amendment’s core protection.
Court Also Raises “Shall-Issue” and ATF Abuse Questions
The order also points to a more recent appellate development. Judge Clark cited the Fifth Circuit’s decision in United States v. Peterson, which held that the NFA’s registration regime is “presumptively constitutional because it is a shall-issue regime.” The Missouri court now wants the parties to address whether the NFA truly is a shall-issue system and, if so, whether such regimes are automatically or presumptively constitutional under Heller and Bruen.
Just as important, Judge Clark asked the parties to brief whether ATF has applied the NFA “toward abusive ends” through “exorbitant fees” or “lengthy wait times,” invoking language from Bruen’s footnote 9.
For now, the order should be read as a procedural development. However, it shows the court is taking a serious look at whether the NFA can continue to function as it has after Congress zeroed out the tax for most covered firearms, and whether the government’s regulation of suppressors and SBRs can survive under the Supreme Court’s current Second Amendment framework.

Laravel Ingest by Robin Kopp is a configuration-driven ETL (Extract, Transform, Load) package that replaces one-off import scripts with declarative importer classes. It handles files from a few hundred to tens of millions of rows by processing them through PHP Generators and Laravel Queues, keeping memory usage consistent regardless of file size.
Main Features
Declarative importer classes using a fluent IngestConfig builder
Automatic resolution of BelongsTo and BelongsToMany relationships
Duplicate handling strategies: SKIP, CREATE, UPDATE, and UPDATE_IF_NEWER
Dry-run mode to validate imports before writing to the database
Failed row tracking with downloadable CSV exports
Column aliasing to map varying header names to a single field
Auto-generated Artisan commands and REST API endpoints per importer
Defining an Importer
After installing the package and running migrations, you create an importer class that implements IngestDefinition and returns an IngestConfig. By convention, these live in the App\Ingest namespace:
For dry runs, append the --dry-run flag to the Artisan command to validate the file and surface any errors without touching the database.
Monitoring
The package includes several Artisan commands for checking on running or completed imports:
phpartisaningest:list# List registered importers
phpartisaningest:status {id} # Show progress and row statistics
phpartisaningest:cancel {id} # Stop an in-progress import
phpartisaningest:retry {id} # Reprocess only the failed rows
Equivalent REST endpoints are also available:
GET /api/v1/ingest — recent runs
GET /api/v1/ingest/{id} — status and statistics
GET /api/v1/ingest/{id}/errors/summary — aggregated error breakdown
GET /api/v1/ingest/{id}/failed-rows/download — CSV of rows that failed
Events
The package dispatches events throughout the import lifecycle — IngestRunStarted, ChunkProcessed, RowProcessed, IngestRunCompleted, and IngestRunFailed — which you can listen to for notifications or custom side effects.
Last year around this time, Disney’s live-action Lilo & Stitch was about to arrive, and fans wondered if the studio would be able to bounce back from its live-action Snow White stumble and resume its streak of hit remakes. And… yep, no problem there. So the live-action Moana will be diving into much safer waters when it arrives July 10, even if this latest trailer suggests it’s basically a shot-for-shot remake of the original film. That includes Dwayne Johnson as Maui, complete with animated tattoos.
This new live-action take on Moana stars Catherine Lagaʻaia as Moana alongside Johnson, who also voiced Maui in the animated films.
Disney also shared a new featurette, “Artistry of Moana,” offering a behind-the-scenes peek at the film with director Thomas Kail as well as Laga’aia, Johnson, and the film’s costume designer and choreographer.
The rest of the cast includes John Tui as Moana’s father, Chief Tui; Frankie Adams as Moana’s mother, Sina; and Rena Owen as Moana’s Gramma Tala. Auli’i Cravalho, the voice of Moana in the animated films, is among Moana‘s executive producers. The film features original songs by Lin-Manuel Miranda, Opetaia Foaʻi, and Mark Mancina, and an original score composed by Mancina.
