Hello everyone :P I made simple spool holder. It's easy to print, and easy to use (; STL files for 628ZZ bearings (8x24x8) and spools with width less then 95mm. Feel free to ask to create for yours bearings. In files source project for Solidworks 2017 , with "params.txt" file. Where you can set your own bearings sizes and width of holder (tube length) and rebuild your own holder, export to STL and print it. For assembly you will need to print: "size_base.STL", 1 pcs "size_holder_(x4).STL", 4 pcs "size_tube_(x2).STL", 2 pcs "size_wall_(x2).STL", 2 pcs P'S : After a few days of use, now I can say - I like it, very useful thing (=
