This is a 3D-printable pen holder that I designed to hold 4mm Molotow Pens. Why do you need these pens, or a holder for them? Mirror-chrome! Both paintable and airbrushable. The holder I designed allows you to keep the pen upright and opened without worry about spilling. Since these pens need to be kept upright once you crack the tip, this holder can also be used for storage.
There's a place for the cap to sit once it's unscrewed and for the internal mechanism to sit once it's removed so it won't roll away and make a mess.
If you'd like to know more about how this ink and holder can be used, you can read about it on my website.
No fancy settings are required to print. Very easy and straight forward.
Designed using calipers for precise dimensions and built in OpenSCAD. This is the second revision of my original design and turned out perfectly!
