Spool Winder for Dremel 3D printers
Winder to attach your empty Dremel spools to an electric drill so that you can wind on refill and third party filaments.
This is best printed in PLA a bit hotter than usual, so that you get good adhesion of the layers.
If you must print in a plastic which does not bond well, such as ABS then there is a hole up through the middle to take an optional M4 x 50mm machine screw to strengthen the layers forming the threads to reduce the chances of them snapping off.
If your printer prints a thick first layer (as mine does) then you may need to trim the edge of the hole in the base with a knife before inserting the drill bit. This is designed to be a tight fit and may need a gentle tap with a hammer to insert it. It should be a tight enough fit without gluing.
