Simple Chipset Enclosure for INL Retro Programmer Dumper PCB v2.0 (APR2018) Later versions of the PCB change the reset and Bootload switch design. Screw holes are designed to accommodate 2.6mm coarse threaded screws up to approximately 5mm long. A light pipe is not strictly necessary, but it does help to make the dim LED visible from an angle. When the LED is fully lit, it's clearly visible from any angle without a light pipe. The debug header version has a cutout for an ARM serial wire debugger, which isn't present on purchased devices as it's only useful for advanced firmware development. The Bootloader switch can be used to update MCU firmware over USB after all. If you've soldered your own debug header onto the board, then you'll want to print that version. A set of light pipes in varying sizes is recommended, as the number of perimeters can greatly affect final sizing. Three perimeters seem to produce optimal results, resulting in 100% infill on the upper/narrow end when printed with a normal 0.2mm layer height on a Prusa MK2S. Two different reset button options are available, depending on whether you want a raised or near-flush design.
