Mounting tabs for 1.3" OLED display
cults3d
These are disposable mounting tabs for 1.3" OLED displays like the Heltec models found on eBay. They're inserted between the display and the main PCB, riveted in place using a hot solder iron's side. The model is customized, but the default STL calls for two 3mm drills on the main PCB. The mounts are eccentric to simplify printing, which requires the PCB hole to be slightly offset from the display's mounting holes center line. Only two of the four display holes use these mounts since the other side is secured by header pins soldered to the main PCB. I printed mine using black PLA on a MakerFarm Prusa I3V with a 0.4mm nozzle and 0.2mm layers, sliced by Cura. You may need to adjust the dimensions to match your printer's tolerances.
