This is expirimental, if you want to test print before i get to please let me know results ;DDD
Based on my previous works, but a new try and risky in some spots ;D this test is a 10mm wrench. Just sharing some of my rough drafts, ill either edit or scrap it lter based on results.
Tolerances are 0.2mm so print this first- https://www.thingiverse.com/thing:3569489
UPDATE: Tested slightly updated wrench. Works great but i saw some room for improvement ;)
UPDATE 2: Uploaded ultra updated wrench. Lets see what happens ;) (redesigned from bottom up, made insides 10.6mm because the 10.4 was tight for me. Tried to be around 1.6mm all around so print 2 walls and it should be great. Quite a skinny wrench but the design should help with ridgidity ;0 idk, its just an expiriment xD)
