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 1970s Leather-Topped Executive Desk with a Built-In Swappable Accessory Rail

https://s3files.core77.com/blog/images/1818845_81_142871_kHbNHRx8g.jpg

Though this was designed in the 1970s, this desk looks closer to modern-day furniture than say, a desk from the 1950s.

Danish designer Alex Linder’s Executive Desk has no drawers, and features a recessed aluminum rail that takes a variety of accessories: A desk lamp, a clock, a calendar, a countdown timer (presumably for meetings), little storage bins and, this being the ’70s, an ashtray.

The user chooses where to place the accessories within the rail.

The desk surface is leather, an unusual choice both now and then.

If this thing was height-adjustable and had appeared on a current-day Kickstarter, I wouldn’t bat an eye.

The New Live-Action ‘Moana’ Trailer Welcomes You to the Rock

https://gizmodo.com/app/uploads/2026/03/TheRockMoana-1280×853.jpg

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.

There’s also plenty of built-in goodwill for Moana as a franchise, including its animated sequel, Moana 2, which was a smash hit in 2024 after being retooled from Disney+ series to theatrical film.

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.

There’s also a new poster today:

Bambu Lab makes the most popular 3D printers in the world, earning a reputation for ease of use, reliability, and great value. But not everyone is in love with the company’s walled garden approach, which involves locking out third-party slicers and a heavy dependence on the cloud.
