micro hinge v1

micro hinge v1 v2

I also designed a mini version.

It rotates 180 degrees in the closing direction and 90 degrees in the opening direction. I added a block that stops the closing angle at 180 degrees and I limited the opening angle to 90 degrees.
total movement angle 270 degrees

dimensions
v1 18x12x6.6mm

I recommend you print with 100% fill. I did not use support.

you need
m2x10mm bolt
m2 nut

if you want to support
