Dupont Jumper Wire Bundlers for Multi-Pin Connectors (TPU)

Update Feb 17 2025

• Moved the original files with a 0.1mm tolerance to their own folder
• Uploaded new files with a 0.2mm tolerance
  • Dupont connectors are 2.54mm
  • Openings are 2.74mm
• Added Configurations
  • 1x3 with filled-in center pin (useful to connect to Arduino Nano power pins)
  • 1x4 with filled-in 2nd pin (useful to connect to Arduino Nano Serial I/O pins) 

I needed to test some new 14-segment displays. It's a pain holding the 5 jumper pins in the right order to temporarily apply them to each display to check it. I designed small bundling adapters that be be used to group pins together semi-permanently.

Designed with little tolerance, to be printed in a flexible filament like TPU.

Included configurations:

• 1x1 1x2 1x3 1x4 1x5 1x6 1x7 1x8 1x9 1x10
• 2x2 2x3 2x4 2x5 2x6

If it's a tight fit, use a small flat blade screw driver or a vise to shove the pins in, center pins last if needed.
