Improved eSun reusable filament piece

thingiverse

I have been using the refillable eSun PETG rolls on their reusable spools. The clips aren't that great for longevity though, so I got rid of them and made my own. I have made these to be used with M3 bolts and nuts, the nuts should stay in place in their slots so that you can assemble the spool and then screw in the sides. Settings shouldn't matter, just print it with something that won't melt or go soft in your filament dryer.
