Friction Hinge (TPU core)
Print Profile(1)
Bill of Materials
Description
This is a small friction hinge that uses a TPU core / O-ring to maintain constant torsional resistance.
Currently, the hinge uses countersunk M3 screws for mounting, and an M3 socket head screw + nylon lock nut to bolt the hinge together.
I used Ninjatek Ninjaflex (it's 85A) to print the TPU core, but most other TPUs should work as well even if they have a higher shore hardness.
Any filament is acceptable to use for the actual hinge frames, I have been using eSun PLA+
Required Hardware
M3 x 18 socket head screw
M3 Nylon lock nut
Countersunk M3 screws (for mounting)
Slicing Notes
The hinge frames print best in the vertical orientation (hinge axis of rotation perpendicular to the build plate). All you need is some small supports under the screw head and nut recesses; these are super easy to remove by pushing a bolt or small screwdriver through the opposite side of the hole to pop the support out.
