i have remodelled and made a great model from @Meistel Edel (thx!) parametric, so any size can be easily created
any width/height
any number of holes
the plate is 3mm thick
Variations:
exported few most common variations for convenient usage
see Blender file for other params
Print info:
4 perimeters - so almost whole body is made of perimeters
brim
it is not needed for low hinges, but to be sure, add brim
50% infill (there is not much of it with 4 perimeters)
Assembly:
❗❕ on 1st look it may look like impossible to bend, but try to bend it slowly on one side and back, repeatidly and after a while it should work nicely.
Parametric design:
connectors_count
the height of hinge
number of connectors on the right side of the hinge
height in cm is always connectors_count-0.5 (so for 5connectors, it will be height 4.5)
