I bought 2 x Shelly2.5 double relay switch which can be used as a remote roller shutter controller. Shelly 2.5 is small but it did not fit in the basic shutter knob I was using. So I designed a replacement in which there is room for the Shelly 2.5.

Print it with your own settings. After the print, turn the Shelly2.5 90 degrees and place it with the small side into the socket. Then turn it and press it in place. Be sure to add the wires first before you place the Shelly2.5.

Please feel free to use this print and let me know if it helped you.

Update 2023-08-03: Added the original Fusion 360 source file and a Ketchup export. (Dunno if this last one is working)
