This is a 1 or 2kg spool holder for Printer Box top side mount works fine with either size (small spools work fine as well of course).. I made this with keeping it as small and light as possible in mind but i needed to put a 2kg spool in it. I made mine from PLA of course Petg would be even better Im sure but it has been working fine for months the pictures shown are with a base that fits on a Printer Box Enclosure but it works fine without it

You need to print
2 spool sides
2 spool bottoms
1 spool top
and need 4 M4 x 16 screws with nuts to attack the 2x bottoms to the sides
