For those of you saying it is overpriced - as someone that 3D prints products on a mass scale, I would consider the following:
- This piece requires 5 different colors of filament (grey, blue, red, black, white)
- The Prints themselves probably takes between 8-12 hours for one complete unit
- The hardware (rods, slide potentiometers, circuit board, microcontroller, flap switch) itself is probably worth at least 20 or more$
- Assembly time
- Packing and shipping time.
All in all - you would have a hard time making it yourself for the same price if you factor in the equipment, filament, and hours.
