Filament Welding/Splicing Fixture (print-in-place, fully assembled)
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
I wanted a simple print-in-place jig to hold my filament steady for welding. Most of the designs on here use screws to hold the clamp together, but the plastic will strip out over time. This design is an easy print for most printers, and will be ready-to-use fresh off the print bed.
For welding, I recommend a soldering iron with temperature control, set to the ideal printing temperature of your filament. Just cut the ends of your filament at a 45° angle and line them up in the grooves. Cover the tip of the soldering iron with aluminum foil and carefully melt the ends of your filament together.
This is the iron I use: https://smile.amazon.com/Soldering-Station-392%E2%84%89-896%E2%84%89-Adjustable-Temperature/dp/B09LH46XX6?ref_=ast_sto_dp&th=1
EDIT: (8/3/22) I uploaded a revised .stl with the correct scale, as the original was scaled for mm instead of inches. (Oops!)
