Timer board cover for UV curing chamber

I have specially designed this part for my DIY UV curing chamber and I printed it with my FDM and also with my Resin printer.
FDM is more flexible but I decided to use the Resin version because of the higher details.

For the wiring I uploaded some close up pictures. If you close the GND and GND- over the SIGN at the right hand side than you can trigger the Timer.

You can check my DIY video on YouTube. In the description you can find the BOM.
