About this 3D model

This is a stacking horizontal spool holder/roller, originally designed for PolyMaker's 3kg spools (120mm wide, 250mm OD, 55mm ID). The parts are broken up with the largest being the tray at 250mm across. A printer with 250mm print area should be able to print all of the parts. To print a single “stack” of this model, just print everything in one of the project files. The part names include a designator for how many you need to print for one spool holder. You'll need 8x FlatBit_x8 3x VerticalSupport_x4 1x VerticalSupportStubby_x1 4x BearingPin_x4 1x SpoolPlate_x1 2x - 4x AlignmentRod_x4 1x your choice of AlignmentGuide##mm_x1 Each spool holder unit also needs 4x 608 bearings (skateboard bearings).
