Evaluation of members on the printability, utility, level of detail, etc.


3D model description

This is my favorite design I have made yet. It is fully 3D Printed and does not require any hardware or fasteners, and also requires no sanding or adjustments to make it work. It has a 4-digit combination that you can customize, and it is quite difficult to pick open.

*note: The Cults3D website does not properly render the number wheels, but it does work fine in slicers and does print.

3D printing settings

I used 0.15 mm layer heights for all the pieces, except for the lock body, which I used 0.3 mm layer heights for. I used 3 perimeters, and 15-20% infill. I did all printing on my Ender-3 V2, and even with only PLA, the design is decently sturdy.
