Hi all!
This model require more metal working than other, but it has nice precision and durability. Knob can be taken from this thing https://www.thingiverse.com/thing:144333
Led 10mm, resistor has to be calculated for you case, I use 18650 battery with DCDC Step-UP and use 2x470R.
Motor is taken from Epson inkjet printer, same way to get rods, you will need 6mm and 8mm.
Upd Fan is installed on China 3.175 drill bit colored belt
Upd CDR lasercut box is included.
