Stackable Horizontal Spool Holder for 1kg or 3kg Filament [V2]

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.

• 1x SpoolPlate_x1
• 2x - 4x AlignmentRod_x4

Each spool holder unit also needs 4x 608 bearings (skateboard bearings).
