Fixed the mess that was my board management (is that how you call it?) by finally adding screws and a stricter fit to the design. Previously I tried adding a spring-like hold on both sides of the…uh…electronics holders?…but they were too loose, easily slid, and simply fell off whenever I nudged the bot a little (left). For the 9v battery holder (with the nano and breadboard on top), I added screws to the sides (I had planned this when I started designing before the summer, couldn’t figure it out, and had useless screw holes at the sides for a while), whereas the buck converter and the pca9685 holder was given a tighter tolerance (given that there were no screw holes in the bot body designed by the past me). Now they no longer fall off when testing the legs, making my life a lot easier (right)! :D!!!
