Gridfinity compatible adjustable jumper/dupont wire comb holds your jumpers. I redesigned the model in FreeCAD. I figured most people don't need the comb holders in the middle since you could print the smaller versions if you needed to, so I got rid of those, and some more while keeping it structurally stable. I currently don't have a base with 3 units of length because FreeCAD freaks out, I am uploading the .FCStd project too if you want to modify it further. I used Stu142's FreeCAD Gridfinity Workbench as a base.

With my slicer settings, the 5-units optimized model prints in 1 hour and 23 minutes and weighs 34.4 grams. The original prints in 2 hours and 5 minutes and weighs 51.8 grams.

Thats a reduction of -33% print time and filament usage. Thats not to say OrdinaryWonder's model is bad, thanks for the original model! I liked the functionality and wanted to limit my filament usage.

In the photos I used @Stefterv_125157's higher density wire comb, link here [https://www.printables.com/model/428684-gridfinity-adjustable-jumper-wire-comb-higher-dens](https://www.printables.com/model/428684-gridfinity-adjustable-jumper-wire-comb-higher-dens)

Slicer settings I used:

• Nozzle: 0.4mm
• Wall loops/perimeters: 3
• top/bottom layers: 3
• Infill: %10, Cross Hatch
• Mouse Ear brims enabled
• Inner/Outer wall printing order to help with overhangs
