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.
You can test this with a simple set of pins and a hollown tube 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,
Edit: it’s different for every printer, even printers of the same brand. It depends a lot on how well tuned it is, and just what the total dimensional consistency is between prints.
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.
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!
