What it does

  • Holds two filament ends steady so you can splice them
  • Print-in-place design works fresh off the bed
  • No screws to strip out over time
  • Saves the tail end of every roll from the trash
  • Joins colors for fun multi-color prints

Stop tossing the last meter of every roll. This filament welding jig holds two filament ends in line so you can splice them with a soldering iron. Use it to save the tails of old rolls or to join two colors into one custom roll.

The fixture is print-in-place, so it comes off the bed ready to use. The clamp is built into the body, so there are no screws to strip out over time. Set the soldering iron to your normal print temperature, press the ends together, and you have a clean joint.

Made in the USA. A simple workshop tool that pays for itself.

What it is made of

Designs like this print well in PLA. Compare the materials.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
