Okay i just printed and tested this..
Not bad...for first attempt at this design
It is very close to other design that we like..very impressed you manage to emulate it.
The hinge could be improve..
the other design has a better stronger hinge..
I notice the hinge between the base and side for the left side would pop out when rotating..
Can you also provide individual pieces STL file so we can print individual parts
That way if you make any improvements we can just print the individual updated part instead of doing the entire lot again.
