MPCNC Pen / Sharpie Holder

thingiverse

Hey Guys, Ryan's design is cool, but it's tough to quickly swap pens without cutting the cable tie and then messing around with replacing it. This design lets you easily tighten a bolt and use a variety of pen or marker thicknesses. No printing support needed, just pause at layer 141 to add an M4 nut (or if you're lazy, unpick the top layer and throw in a nut - easy!). Thanks to @fyloe and @daGHIZmo for their original parts; I've mashed them together to create this. Cheers Rob.
