For printing I had Overture Black PETG loaded up already, and I figured PETG would be a good choice for this. I am running a Prusa MK4 with a modded enclosure. Specs:

• Prusa MK4 with .4mm Nozzle and Latest Input Shaper
• Overture Black PETG with Generic PETG Filament in PrusaSlicer
• Layers and Perimeters adjustment on the Base to 5 perimeters. This was to keep input shaper from nearly chunking the entire enclosure off it's stand while printing the infill in a rectilinear pattern. Smooth concentric perimeters worked much better. 
• 100% infill. This is all that I tried, and I believe it to be necessary. 
• My print time for 1 base and 3 guides was 2 hours and 8 minutes. 

This is my first model that I have taken from idea to reality. I am very proud of the end result, and would appreciate any helpful feedback. I started out making a guide for one hole in a specific spot for our cabinets at home, which led me to this as the day progressed. I struggled with the numbers a bit, and we will call this “wabi sabi” rather than an error. 

I had some other ideas for this, but somebody may be able to make them faster than me with a remix. I will upload more as I have time. Some ideas:

• Imperial Version
• Larger Base / More Holes
• Different Spacings / Patterns
• Magnets
