About this 3D model

Simple holder for 1kg spools. You will need two spool-center-parts and two side-parts printed. Additional needed (to fit spools with a width of 90mm and a diameter of 160mm): two 626-size bearings, three threaded rods M6 each 110mm long and 8 M6 nuts and 8 M6 washers. Just fix the left and the right holder-part with the nuts as shown in the last picture. Then you can drop the spool with the inserted spool-centers and the last threaded rod from the top into the stand. Normally the bearings should have a tough fit. If you like they can be fixed with three M3x10mm bolts and nuts on each side to prevent them from slipping out of the spool-centers.
