Labrat ideas for fun 3d lab/science gadgets?
I have access to a decent 3D printer, and I’m trying to come up with small, science‑y things to print for students and a few early‑career friends.
I’ve looked online (Thingiverse, MakersWorld) and seen everything from tube racks and pipette holders to little molecular models and mini lab equipment -- but I'm mostly curious what people here have actually liked in real life, things that didn't just end up in a drawer, and made you think "okay, this is actually pretty cool"?
Bonus points if you have links to designs you like! I'm happy to share a list of what I've found so far in the comments.
