I woke up to this. 3D printing finished just before the filament ran out. only 8mm was left before extruder. All the 3D printing gods were with me tonight 
Go and buy a lottery ticket 
I look at the spool, all filament gone I was like FML. I looked at print, it looked finished, hm weird. I looked in the extruder and there was still 8mm left, I was like waaaaaaaaat?
Have anyone built a tool to melt and connect two filaments ?
Yes Richrap and others
@Sebastian_Schmidt
I’ve tried unsuccessfully several times. A specialized tool would need to be made to “crimp” the filament at the binding point to keep it within +/-0.05mm or something. Every time I’ve tried it clogs at the joint.
Maybe it’s because Rich was using 3mm filament?
@Michelle_Sleeper yes i was also thinking on special tool.
Maybe we can steal ideas from glassfaser?
