I printed the parts, including a spare nut arranged directly on the build plate without supports, which turned out great. After cleaning and curing, I tightened the printed nut on the threaded stalk. I added M2x12mm, though ten-millimeter bolts would have been better. The base and lid fit perfectly, but I forgot to check the pinout before installation.
I installed a screen and attempted to connect it with an Arduino but accidentally burned it up by switching the power cables. When I tried to mount a non-identical spare screen, I discovered that the hole patterns were off by a couple of millimeters. After realizing my newly ordered screens were much larger, I adjusted the OpenSCAD code and modified the riser size to accommodate the tall inductor on the larger screen.
I printed mounts three screens. The smaller mounts fit well, but the larger screen lid did not because the PCB hung over too much. The lid is not essential, allowing for a print of just the base and a nut to mount the screen with shorter bolts, keeping the electronics exposed.
I added some nice-to-have features to the program, like a variable that lets me expand the lid and mount in case I have a large screen with a PCB that hangs over. I made the anti-rotation peg exactly 20 mm from the center of the threaded tube, so drilling mounting holes should not require much guesswork.
I installed a screen on a Rock Band controller for an upcoming project. I was happy with how it fit and looked, with the white bezel on a black body with a white pick-guard. I connected an Arduino and ran the demo program without a problem.
Whenever I printed a screen mount and nut, I struggled with the nut fitting too snugly onto the stalk, leading to cracks when attempting to force them together. I discovered that the threads did not align due to differing thread-per-inch factors. By hardcoding the "pitch" for both components, I aligned the threads correctly, and the new nuts fit. However, I realized my tolerance was too high, causing significant gaps, so future prints will have improved fits.
The rest of the summary posts have been arranged by date.
