eSUN eSpool Screw

thingiverse

I use a lot of filament and was getting concerned about the large number of plastic spools going to waste. So I started to use refillable eSUN espools. While they are very easy to put together, I really struggled to take them apart. I solved the issue by removing the two plastic clips on one side of the three plastic spacers and using this screw to hold the reel together. I have also inserted two 6x17x6 ball bearings that slide onto a 6mm screws on the printer, acting as the filament holder.
