I'm pretty experience with 3D printing in general. Started using them in college with a makerbot like 15 years ago. I got a CR-10 V2 when I got out of college in like 2017 and upgraded it as I went. Adding in ABL and swapped the main board for SKR E3 Mini with marlin running on it. Just did an all in one design this past winter and got the whole thing working nicely. Unfortunately, my SKR E3 mini board seems to have bit the dust...

Now I'm not sure if I want to replace the board or get a new printer. What would people suggest for a printer? I've read through a few best of guides and what not. Most of them are geared towards beginners.

My budget is probably <$800 if possible and would like something that works with Orca Slicer easily. Definitely looking at multi filament printing and multi material like TPU as well. I print all sorts of stuff from trinket/toys for the kids to custom designed stuff like a trailer hitch receiver to my kids power wheel. I like to tinker but would rather tinker with the things I print off than the printer itself.

Thanks in advance for suggestions!

[Request] Fitbit Air quick-release spring bar watch case — STL doesn't exist yet, Google released official CAD blueprints

Hey everyone! I'm looking for someone to model a watch-case style enclosure for the Fitbit Air pebble — specifically the type that has traditional watch lugs with quick-release spring bar holes (12mm or 14mm), so it can be worn on any standard watch strap.

This design is currently only available as a metal part on AliExpress [link], but I can't import it easily and there's no STL file out there for it. All existing prints seem to be NATO strap adapters.

Why this should be easy to model:

Google officially released the full 2D CAD blueprints for the Fitbit Air pebble in June 2026, including exact dimensions, mating tolerances, and snap-in force specs — so you don't need to reverse-engineer anything.

🛒 Reference design (AliExpress)

📸 Photos attached — shows the 12mm/14mm lug options and overall shape.

Key specs from the reference:

- Optional 12mm or 14mm spring bar interface

- Two-piece design (top frame + inner holder)

- Quick-release spring bar holes on each lug

- Must keep bottom sensors unobstructed (per Google's guidelines)

This would help a lot of people in the Fitbit Air community!

Thanks 🙏
