3D model description

Hi,
This is a two lever steampunk type dimmer as shown in pictures. I've printed these parts on my creality ender 3 with standard settings. They are designed with some gaps so that they fit together snuggly. Suggest 100% infil for durability, especially with kids around.

You will need to print as follows:
1x case bottom.
1x case top
1x center cover
2x pot holder
2x end caps
2x lever body
2x lever shaft
4x side
4x pcb holder (optional)

I've used two 10 kohm pots and held them in pot holders with super glue.
I've cut shimms/washers (not shown in pictures) from thin plastic which are placed on both sides of levers just around shafts - this way levers are nice and tight in bottom, but movig without rubbing on th eoutside.

There is a little piece of metal forced in to the shaft with heat and attached with super glue, it extends towards pot to turn it with lever. Also suggest that shaft is glued inside lever.

After putting it all together I've used screws to attach sides to the top cover, but super glue is another option.

For circuit - I've used generic universal PCB (https://www.amazon.com/Double-Side-Prototype-Universal-Printed-Circuit/dp/B075ZF4YG4) and designed dimmer using arduino.

There are plenty of materials online on how to do it.

This is my first entry here, so please go easy on me :)
I have few more projects to go in near future.

Hope you enjoy.
