This is the control console for the DAV5 V3.01 Raman spectrometer, I designed it on FreeCad v0.16. I will be having this 3d printed by Sculpteo using POM material (powdered nylon type material,) color [white] for about $107.00US, as always, all my 3d parts are manufactured by Sculpteo and I have over 236 designs uploaded to their website at my personal shop their.

This console utilizes a 1 x 4 keypad matrix # pad, to control the functions of the diffraction grating that is mounted on the triple turret.

Adafruit Membrane 1x4 Keypad

This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required - just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot.

Dimensions 2 x 1.2 x 0.1 inches
