Comment on I made another Hockey Team Keychain

Just curious, when making this how much tolerance did you account for? I want to make some for baseball teams, but wasn’t sure how much to add.
On my ender3 it was somewhere between ±0.05mm per wall. But with my Prusa MK4 I didn’t add any.
I would say to do a test print first and see how well it fits. For me smaller parts are quite snug but fit well enough while larger prints require some glue to prevent them from coming undone.
.05 on my ender 3 s1 sounds perfect based on the tolerance tests I’ve run. Thanks!

You can test this with a simple set of pins and a hollown tub to fit. In anything that lets you define parameters, just set the pins to something like [diameter] - .01x[1, 2,3,4, etc]
The other tip here is to make the parts slightly trapezoidal in cross section, so they start easy and only really pressfit tightly the last bit,

Thats a very fair point. I’ve done tolerance tests with mine and can get away with 0 with some encouragement and .05 just fine. Thanks!

Yeah, gotta be careful with tolerances from others… speaking from experience.
More, uh, “experience” than I care to admit.
