I had an idea today. I was tired to scrap en of roll filament, just because the remaining length was too short.
I tried to weld it by hand by heating it, but it did not work.
At work, I asked a friend to mill a small block of brass, cut it in half and then, to drill a 3 mm hole just in the middle.
I have to find a way to clamp the 2 parts together, insert a heatblock coming from a extra hotend I have, and a temp sensor.
Here the picture of the first part ;-)!
This technic could be use to prevent from scrapping filament, and also to combine colors!
See you soon
