FrankenHolder - pen/tool holder

Use zero top layers to expose the fill and hex infill to customise the hole size. 10% fill makes 18mm holes, I found 15% giving 12mm a good size.

The pair are at 100% scale and the larger one at 150%

Derived from cerberus333's Frankenstein's monster bust

The red one in the photo is mizliz's Frankenstein Walker, watching the hex fill while printing it inspired the holder idea.
