TIG tungsten electrode tip grinder

thingiverse

This was somewhat inspired by a different remix of jag's design, done by entityunknown - in which he made a bunch of modifications to make it easier to install or remove the diamond wheel while the fixture is installed on the dremel. I like the idea, but I hate printing with a lot of supports if it can be avoided - and I found that it printed quite badly without them. This design modifies jag's with a different approach, by splitting it into two pieces - the base threads onto the dremel and is low-profile so you can access the collet, and the cup threads onto the base after you've installed the diamond wheel in the collet. Both parts print great without supports. The electrode holes are a little oversized, but mine still needed a quick pass with the appropriately sized drill bits (1/16", 3/32", 1/8") after printing. This one is sized the same as jag's, meant for 40mm diameter diamond discs such as [these from Amazon](https://smile.amazon.com/dp/B07BNMDP53/ref=cm_sw_em_r_mt_dp_U_Pet6CbHV6KE2H) There are a few weird artifacts on the internal thread of the base that came from the modeling process, but they are insubstantial so slicers should ignore them.
