Probably wanna post in !general@forum.guncadindex.com, friend. This is the general-purpose 3D printing community on lemmy.ml. It's like posting to /r/3Dprinting instead of /r/fosscad.

Fwiw I still haven't gotten a response back from the mods about whether gun stuff is allowed, but it's probably best not to bug the normal folks here if we don't have to.
