RAM-Compatible mount, Reinforced

thingiverse

I'm skeptical about the durability of FDM-printed models, especially when it comes to layer adhesion versus torque in thin members. Most of my prints have been problem-free - I even printed a 75mm Companion Cube in PLA that's become a favorite stress-reliever as I whack it against desks, leaving onlookers stunned. Still, several working parts have failed due to layer delamination. I'm intrigued by the idea of DIY RAM-compatible components, but the real thing is made from metal, which offers far greater durability in this application. So, why not add a bit of metal to these DIY components? Supports might be tricky here; they'll be needed within the recess for the screw head, but hopefully won't be required elsewhere. I'm unsure how the M6 threads will turn out without it, but cleaning supports from the threads would be a nightmare. To sidestep this issue, I designed the 1/4" model with a recess for a 1/4-20 hex nut. It should be deep enough to use a Nylock nut with a 1/4-20 x 1.25" pan head machine screw. The two M6 models are designed for pan heads and socket heads, while the experimental M3 version uses an M3 reinforcement screw and adjusts all mounting holes to take an M3 screw and washer. I plan to further develop this concept. I'm curious to see how well the base plate holds up (may want to explore a mending plate reinforcement) and whether or not the nut opening causes any problems with the arm grip. If the threads don't print well without support, I'll try a smooth-bore and set the screw or another sort of rod in epoxy.
