rail spool system

thingiverse

I'm planning to build a custom rail system on the bottom of a shelf, where individual arms can slide over the rails for various spools. I'm also creating a bowden motor mount that attaches directly to these rails. Notes: Double-sided arm printing poses a challenge; I've tried multiple orientations but haven't found an ideal solution yet. Vertical printing is tricky due to the locking parts' strength, so I prefer horizontal printing. I'm using skate bearings for this project. Print Settings: Printer Brand: Prusa Printer: Prusa Steel Supports: Yes Resolution: 2 mm Infill: 15% Notes: I use Simplified as my slicer and print host. Material: ABS My temperatures are set to 230/100. Arm Left/Right: Infill: Fast Honeycomb, 10% Additions: Skirt, 5 layers Locking Pin: Infill: Fast Honeycomb, 20% Additions: Skirt, 2 layers Rail: Infill: Fast Honeycomb, 10% Additions: Skirt, 5 layers Overview and Background: I'm currently testing this project. Lesson Plan and Activity: Please share your tips and suggestions; I'd appreciate the help. This is my first 3D printing project.
