Filament Joiner
thingiverse
New design. Weld the knurled knobs onto 4mm screw/bolt. Snap square nuts into the bottom part - superglue them in. I used a couple of 14mm bolts that came as extras with my Prusa Mk3s. Screw the filament ends tight and hold the gap over a tealight or candle flame. Squish the ends together until cool (or hold the device legs together with clothes peg or similar). Open the device arms and trim the squashed bulge - sand smooth. If you found this useful, please donate what you think it is worth to paypal.me. Help cover the time of design. Thanks, Enjoy!
