Snap fit case for Gravitrax lift with PWM and USB

Just a small case to mount a PWM and a USB Board for powering a motor (in this case a gravitrax lift. No more fiddling with a battery case or empty batteries. Just plug in your existing micro usb power supply and let your kids control how fast the lift is going.

My components:

• https://www.amazon.de/gp/product/B081JNKDJB (DC 6V 70 RPM Motor GA12-N20)
• 3mm Screws for mounting electronic parts. No inserts, just screw them in.

The fantastic modular lift (you can use any other if you like):

Notes: 

• the PWM also has a real “off” setting (just turn the knob full to the left). 
• the PWM shows if it's “on” or “off” (status LED)
• the pictures display my first version. I added a small hole for the status LED later, which is included in the model here.
• printed without support.
