I have remixed the fantastic work from chiz and made my own version. I changed the original design for some reasons:
1) here in Australia I couldn't find the same items in the original BOM - found different items from KMART or spare parts of previous projects
2) I wanted something simple that I could control with switches instead of the automated programs
3) I was not a big fan of the tupperware look as I will keep this device on my desk.

I have just posted some photos and some of the parts designs. If I see that someone is interested I can prepare more detailed instructions/BOM.

As the original Polysher or the version from chiz it only works with PolySmooth filament, and ethanol higher than 90%

After some tests I decided to add a small fan to create an ethanol airflow that made the polishing more uniform, and mounted it on a support I designed with a good angle to optimize the flow.

The main items are (I will post the urls if someone from OZ is interested):

• Plastic top - food container 4liters from Kmart
• Wooden bottom - bamboo container from Kmart (I will make a printable version as well)
• Lid/plate/base - printed
• 5v stepper motor + driver - Amazon
• Stepper holder - printed
• Arduino (nano or due) - Amazon
• 2 Standard Switches - Amazon
• Button - Amazon
• Button cover - printed
• humidifier - MINISO shop 15$ disassembled (any 5v humidifier is fine, same as one from chiz) with its own liquid container
• Shaft (8mm metal standard shaft) - Amazon
• Shaft to base connector - printed
• Shaft to motor connector - printed
• 12v fan - (powered at 5v to run slowly) Amazon
• Fan mount - printed
• 5v power supply Amazon

The inside looks a bit messy cause I kept the wires very long, so that I can disassemble the plate more easily. The actual wiring is pretty simple, I will provide it if anyone needs it.

NOTE - I am still in the process of publishing the stl files.
I am also planning to replace the bamboo bottom with a printed version that I will publish.
