This is a customizable generator of standoff to mount two lead LEDS above a PCB. I find it more convenient than ordering them from Digikey (e.g. part number 36-7363-ND) because I can easily iterate tweak the dimensions, printing them myself.

I am printing them in ABS, using a Flashforge Creator Pro with PEI build surface and Simplify 3D. Because of the small size of these standoffs, I am getting much better result when printing few of them at once, because it allows more cooling time between printing each layer. If I try to print only a single one, all I get is an unusable blob of ABS.
