Jumper T20/T20S Nano external module adapter

Will not fit Gemini version because heatsink is different.

To actually make this, you will also need connector PCB. This model is created for one like in the pictures – “Jumper T-Pro external module adapter” on aliexpress or this. The wiring in this adapter is not compatible with T20 external port pinout so you will have to re-solder and rearrange wires like shown in another picture. You will also need at least 2 M1.5x3 screws to secure adapter to heatsink.

I recommend printing this with 0.12mm layer height and temperature resistant filament like PETG or ABS.
