CNC Pen Holder
thingiverse
My version of a common type of pen holder for CNC mills. No need to remove your router/spindle as this will fit in the collet. Will work with different diameter pens. Currently two versions, one for a 1/4" shank and the other for a 1/8" shank. Print Settings Printer: M2 Rafts: No Supports: No Resolution: .3 Infill: .2 Notes: I tried a couple different orientations, and it prints pretty well without supports. Post-Printing Supplies Aluminum (or other) rod with shank diameter, cut to length. Two shaft collars for rod. Compression spring - I used a 7/32" for the 1/8" shank and a 3/8" for 1/4" A couple of M3 screws to secure pen.
