PWM Module Bracket

PWM Module Bracket

I designed this little bracket to house 4 PWM modules purchased from Amazon. They control the speed of the motors that run my watermill, engine house and cranes on my model railway.

The potentiometers are mounted about 3mm too low on the PCBs so this bracket incorporates slots to accommodate the end of the PCBs.

I have updated this slightly as I found the PCBs vary slightly. Hopefully, this revised design will improve the fit. (I have not had an opportunity to test print the revised version as yet as I'm waiting for a part for my printer.)

I hope the design will be useful to someone. Any issues, please comment (politely) and I will attempt a fix.
