Collapsible Cup Holder/Pad
thingiverse
Printed as a one-piece cup pad, this item can be used also as a holder for 9 cm high paper cups filled with hot coffee. The collapsed holder is practical for transportation. Update: V2 has improved joints, tuned tolerances, smoother edges and backstops. If you think hinges are too tight, try printing collapsible_holder_v2_looser_hinges.stl. Print Settings: Printer Brand: RepRap; Printer: Prusa i3 MK2; Rafts: No; Supports: No; Resolution: 0.2 mm is sufficient; Infill: Does not matter. Notes: Some short bridging required. Print time is approximately two hours with 0.2 mm resolution. Use finer resolution for smoother joints. Quality filament is recommended, PLA is fine. Post-Printing: Do not risk breaking tiny parts. Joints are rather tough after printing, so be very careful when expanding the holder for the first time. Do not force it to open; instead, gently move parts in small angles first. You might want to clean up your holder from tiny filament hairs before opening it.
