Does anyone have any recommendations about how to combine leftover filament?

I’ve got 3 spools that have a pretty good length of filament left on them but of course I have no idea exactly how much. If I can combine them, I would have enough to finish another print.

Hey chasearch07,

You may be able to use acetone to merge your filament together although I’m unsure of how effective it would be. If you leave filament soaked in acetone it should go sticky and pliable. You may then be able to connect them and file down after it has set. I’ve never tried this so cannot guarantee success.

Hope this helps.

I weigh a similar empty spool and then weigh the spool of leftover filament and typically can make a good estimate to amount left from that. Then use that up on small items that I know there will be enough.

Joining the ends together will most likely turn out poorly since there will be a bump there that could catch in extruder and also it would be weak there and possibly snap during the bends to reach extruder.

You could also just watch the print, pause, and carefully swap in the other roll
