Basic magnetic cupholder I used when I drove haul truck. Stayed on the doors and cab through large bumps without issue. I recommend ABS if you want a tough one but PLA works just fine. I found PETG to be too brittle in cold weather. Printed anywhere from .42 to .1 layer height with no issues (Prusa mk3s and Bambu X1C). Magnets are slightly recessed. I recommend using a ductile adhesive like hot glue or gel adhesive to hold the magnets in as the flex of the plastic will break brittle adhesives like super glue. I also recommend very thin adhesive-backed rubber tape to keep the cup holder from sliding around (gorilla duct tape also works great). I used 60x5x10mm neodymium magnets
The Contigo versions have drainage holes on the bottom.
Hardware:
- 3x 60mmx5mmx10mm neodymium magnet
- Adhesive Backed Rubber
Printing:
- Upright orientation
- 15-30% infill, Square/Grid/Lines
- No supports needed
- Any non-flexible material
Assembly
- Use a liberal amount of glue/adhesive so the cavity is filled after the magnet is inserted
- Recommend flipping the middle magnet so the outer two are attracted to it
- Put any ferrous metal on the inside of the cup when left for drying. Curved files work great for this. Magnets are not recommended for this
- Scrape-off access glue so there are no high points
