Edit (2/12/14): Notice!!/Product Safety Recall :P
Last night I broke the front hook, because I tilted the rifle too far outwards while removing to show a friend. 50% infill printed with the hook pointed up is NOT enough plastic! If used gently it can still work with the hook pointed up, but I recommend printing with supports, lying flat on the table so the layers are mostly identical, and in ABS so supports can be easily removed for maximum strength. For those interested in materials science engineering (I almost did a minor) or the study of composites, this illustrates what a difference grain direction makes for anisotropic materials.
Fortunately I heard a crack of layer delamination just before failure and immediately moved my hand on the rear of the rifle upwards, so when it broke the front swung down barely missing the matching wooden nightstand! Phew! That was close, good thing I keep my display rifles unloaded and without the bayonet attached despite the temptation :D
Mount your antique WWII rifle on your wall for some historic decor with a touch of modern fabrication/prototyping techniques!
After a quick search returned not much that I was comfortable using to hang a heavy wooden rifle over/near my bed, I quickly made these. Simple yet elegant (kinda). Use it to mount a Mosin Nagant or other rifle or object shaped like a rifle to your wall. I am not responsible for any injury or damages if your print or mounting option is insufficient for supporting the weight of the object you hang on it.
Having said that, I printed mine with the hook pointing up, which is weaker than on its side for this purpose, using only 50% infill and it hasn't fallen yet.
Print both front and rear hook, the larger diameter one is for the rear which is wider. They are designed so their center's are lined up when both mounted flush to a surface.
I used .15mm layer, 2 shells, 50% infill, and ABS, but I would recommend more material to be safe. Mine hasn't broken yet, however.
