An holder for an optocoupler. It saves space as it fits vertically on the 2020 frame side.
Remixed from the source to make it compatible with 2020 frames and make the optocoupler stay fixed, with the pillars high enough not to let the board coupler move around.
Print this along with the "Tapa_Optocoupler_V2.stl" file by the original author.
21/08/2019: Added versions with holes for M3, M4 and M5 screws/tnuts. On the 2020 profile M5 is recommended.
Amazon Basics PETG
Please, do use PETG or ABS, due to the pillars and the high temperature.
