UM2 Front door hinge and locking knob

thingiverse

I made a door hinge and locking knob for lions' acrylic front panel on the Ultimaker 2 aluminum extrusion printer. The hinges are designed to work seamlessly with the holes in the front panel design by lions3 from Thingiverse. You can use filament, specifically 1.75mm material, as a pin to secure the two halves together. This flexible filament is tight enough that it can be used on either side without falling out, yet loose enough for smooth opening and closing. The locking knob features a hex nut at its back (inside) that synchronizes the front and back latches effectively. A small screw hole is deliberately designed to be tapped or self-tapped. While there may be occasional separation issues, overall this system functions satisfactorily. For assembly, you will need: M3x10 flathead screws in a total of eight. An M3x25 (or 22) socket screw for added security. Five M3 nuts for additional support and tightness. Four 2020 T-nuts to complete the hinge's structure securely. Filament is used as the flexible pins. I printed the components using ABS, with precise settings at 0.2mm layer height and a moderate infill rate of 20%. Due to its compact design, no raft or support material was needed for this print job.
