While assembling my Kossel 2020 I inevitably ran into issues stripping the Chinesuim M3 bolts that came with the kit. Now that I plan on upgrading to a new extruded I have came to realize I have to replace many of my moving parts because I can not remove the bolts. So I am wondering where everyone buys their bolts to avoid issues with stripping. I’ve used Fastenal before, but being a distributor it’s hard to buy in reasonably small volumes. http://ift.tt/2a52fNC
