No-STL pen holder

A very simple model, just created with a few commands in the PrusaSlicer without importing a STL!

How to do it (for the provided gcode file):

1. Open PrusaSlicer
2. Right-click in the right bar, choose ‘Add Shape’ → ‘Cylinder’
3. Change the scale from 28-something mm to 100mm for the X or Y, the others should change in size as well. You can of course change the size to anything convenient.
4. Change the print settings to '0 top layers'
5. Change the infill to ‘5%’ and ‘Grid’. Just check if the resulting tubes will be wide enough for your pens.
6. Print

You can of course use the gcode file I provided, but maybe you want something thinner, or squarish, or smaller (and thus more) spaces for pensils? No problem!
