Stand for BIG filament spools

This is a support for my big spools (2300g)It's designed for a spool that is 300mm in diameter and 100mm in widthIt uses bearings that are 22 mm diameter, 7mm in width and 8m inner diameter.For wider spools you can simply make the “lock” longer.You need 4 bolts and 4 nuts for the assambly, as well as 2 “locks”. If you don't have experience with PLA strenght tuning print the nuts and bolts in PETG just to be sure.You can glue it togheter, the tollerances are pretty loose, but I wanted to be able to take it apart because I don't use big spools very often.
