bushings for engraving pens on a rotary
thingiverse
made these so my pen body is propped up on the rotary tool for my laser engraver. This is for using a 7mm pen mandrel. I use the CA bushings as they are very snug to hold the turned pen blank and the bushings all together. This should prop up most sizes of turned pen blanks. 30mm diameter, 15mm tall, 7mm hole I printed both at once. created in Onshape free version https://cad.onshape.com/documents/908b711a65081b2cd48f78c5/w/ea9ca7ed3394048c144ac248/e/f9a365780f8c3c36e569063b
