Sustain Pedal for an electronic piano

The pedal-jack must be connected to the outlet of the piano marked with "Sustain Pedal" and not to "Phones" or "Line out".



3D printing:
1 - Sustain Pedal
1 - SustainBase
1- Caps

You need one of the following

  • 2 screws 5 mm in diameter, about 20 mm long
  • Tube 5 mm in diameter 40 mm in length

You need You also need

  • 1 Jack plug
  • some wire 1-2 meter
  • Some wire
  • two springs

It is possible that the hole must be drilled up if screws or pipe is too big.

The pedal functions by connecting the wires together when the pedal is depressed.

The wire consists of two conductors. One will be connected to the spring and the other connected to the metal wires at the end of the pedal.

This must adjust so that there is contact between the leaders when the pedal is pressed and the contact is broken when the pedal is released.

I bet this would also work well as an electric hi-hat pedal! I'm definitely going to have to try this out.

I think this will work well if the link is not reversed. The pedal should break contact when pressing on it. My keyboard is checking when I turn it on. If I press the pedal down on start it working the opposite.

Yeah, most devices just detect whether it's common-open or common-closed by where it is when the system is turned on. I'm not sure if my drum module is that smart though.

It is possible to mount the spring under the pedal and when they should be common-closed i think.

I'm having problems printing the Pedal part. Any suggestions on orientation or supports?

Sorry but uPRINT create support material automatically so I do not know how to do it. Is there a separate stock STL file or a separate file?
