Arduino Uno R3 Bumper

thingiverse

Arduino Uno R3 Bumper * Built from scratch, drawing inspiration from Eric Chu's pioneering bumper design. * Enhanced with increased robustness, featuring a wider raft and tighter dimensions for optimal performance. * Strategically recessed areas accommodate soldered pins with ease. * Engineered specifically for STEM classrooms or laboratory settings. * Mounting holes compatible with 4-40 or M2.5 taps, complemented by a thin bottom skin for precise punch-through installation. * Designed for effortless snap-fit assembly without the need for screws. To secure the Arduino Uno R3 Bumper in place, utilize a hand drill equipped with a #40 bit and a pin-vise, followed by tapping (alternatively, you can employ a 4-40 metal screw). For a polished finish, insert 3/8" or longer black 4-40 nylon screws and trim the excess using an x-acto blade. If the Arduino Uno R3 Bumper does not snap into position smoothly, apply a scale factor to the print; I have successfully used up to a 1.004 scale factor for certain boards.
