Modular Phone Holder and Arm

thingiverse

This is a versatile girder system designed for attaching an adjustable phone holder arm to your table. You can build 1-3 sections of girders to create a joints system. It's highly recommended to use PETG for everything except the base table plate - PETG is more resistant to bending and isn't slippery, especially important for joints. ABS, on the other hand, is slippery and makes it easier to turn the rotating table plate part. Instructions for 3 sections long arm: * Print all three rotating table plate parts using ABS at 60% infill. * Print the swing joints using PETG at 100% infill - 4 x female side.stl, 3 x adapter.stl, and 3 x male side.stl. * Print the phone holder parts using PETG at 100% infill - 1 x bottom.stl and 1 x top.stl. * Print the girder plates using ABS, PLA or PETG at 100%-20% infill - 12 x girder plate.stl. Other hardware: * A pile of M3 bolts in lengths of 8, 10, and 12 mm + M3 nuts. * 4 x M6x30 bolts + nuts for joints. * M6x40 bolt + nut for phone holder. * Screws or bolts up to M6 to attach table plate on. Other notes: * Printing temperatures - use your preferred temperatures for specific materials. I use: + ABS - 240°C nozzle, 110°C bed, enclosed. + PETG - 235°C nozzle, 80°C bed, preferably enclosed. * Layer sizes - 0.2 is what I chose, but others could be possible. * Materials - ABS can also be glued together for additional strength using acetone. * Post processing - annealing (optional) can benefit this thing. It's structurally important and doesn't require much dimensional accuracy. After that, they can be drilled to size if necessary. Different parts should deform evenly if treated together, so they'll still match.
