These models are part of the "KontinuumLAB Instrument Kit" project.
I used these keys for my prototype K.L.I.K. MIDI melodica. They function as simple digital switches, by closing a circuit when pressed. The durability of the self-flexing part was tested on a single key, and was still running at 2 million repetitions, although the key was somewhat deformed. The set contains a full octave of "white" keys, and a single "black"
In the photo, these keys have been combined with a box made using the "box ends" from the KontinuumLAB collection.
For full description / explanation, go to the KontinuumLAB YouTube channel: https://www.youtube.com/channel/UCSvGhrAVvAKpWMsooCTBWZQ. This is the video about the K.L.I.K. melodica specifically:
All of the KLIK instruments are meant to be built using the KontinuumLAB Instrument Kit electronics. The use of 3d printed parts is optional, all instruments can be hand-made as well. I will be selling the "K.L.I.K." kit, as well as instruments based on it, in the webshop at: www.kontinuumlab.com
The 3d-printable parts include: mouth pieces, breath sensors, self-flexing melodica keys, wind instrument keys, structural pieces, end pieces for making boxes, membrane instrument "drums", string instrument fret-board sensor bases and even a fully 3d-printed MIDI ocarina.
The KontinuumLAB Instrument Kit is still under development, more detailed descriptions, as well as updates and more designs will be published right here.
Materials and methods
I print all of these in PLA using my Ender 3, FDM machine.
Layer height 0.2 or 0.28 mm
Support is needed for some pieces, some need to be rotated before printing
Most pieces are meant to be combined with other materials to make the finished instrument. My versions of the KLIK instruments use mainly corrugated cardboard or polypropylene.
