Universal Filament Spool Holder
thingiverse
This is a remix of an existing Spool Holder I found on thingiverse a while ago. I'm so sorry I can't find now the original one so I can't take credit for this, but I think will help to many others. Now the size of both threaded and nut cones are bigger so it fits all of the spool inner diameter sizes I've used since. It combines with my Ikea Platsa Filament Spool Holder-Holder (yeah, twice holder :)), but it can be mounted on any other ways, just use your imagination. I'm attaching a mounting sketch. Extra parts needed: 2 * 608ZZ ball bearing 1 * M8 threaded rod (cut at needed length) 3 * DIN934 M8 Nut Printed with PLA at 0,28 layer height and 20% infill. You should make some tests with the horizontal expansion in order to get a nice sliding betweeen the cone nut and the thdreaded cone. I recommend not to tight both M8 nuts together too much or you will have too much friction between the ball bearings. I also recommend to hot glue the outer M8 nut to avoid the nut to loosen up (or you can use a DIN985 lock nut instead).
