Key Holder Free 3D print model

H: 51.95 mm, 2.045 inW: 50.40 mm, 1.98 inL: 51.95 mm, 2.045 inRecommended Infill: 25-30%I have a family that always seems to lose their keys, so I designed a key holder and decided maybe other people have this problem. This is my first design I am selling so let me know if I should make some upgrades. I made it so that it can be held up by thumbtacks and can hold at least 4 key sets.It can probably be used for holding other things, the diameter of the upright rods is 18 millimeters (about .71 inches) each.
