Pen Holder - Retraction/Stringing Test by MrAmericanMike

Last crawled date: 4 years, 7 months ago

The idea is to print this instead of the regular stringing/retraction test that is more common, but with this one, at the end we get a functional print, and even a nice gift.
Newer version from August 3, 2017 is wider so it holds pens better.
