Enclosure
Use the files below to either laser cut/CNC/print-on-paper-to-cut-and-drill-with-hand-tools or 3D print the enclosure and LED defuser.
The .svg file can be used for cutters, the .stl for 3D printing, or use the .3mf file for a preset slicer layout in Bambu Studio or similar.
LED Diffuser
Fit the LED diffuser strip into the cast top as shown. Affix it using a few drops of cyanoacrylate glue (CA, super glue) from the underside.
Fasten NeoPixel Sticks
Mount the NeoPixel sticks to the underside of the case top as shown using twelve sets of M2.5 x 10mm screws and nuts.
QT Py Mount
Fasten the QT Py mount as shown using four M2.5 x 10mm screws and nuts, with the USB port slot flush with the back of the base.
Encoder Standoffs
Connect four M2.5 x 8mm hex standoffs to each encoder board as shown, using M2.5 x 4mm screws.
Connect Encoder Boards to QT Py
Use a 100mm STEMMA QT / qwiic cable to connect the QT Py to the rotary encoder seesaw breakout boards.
Top Plate
Press the top plate onto the sixteen encoder shafts (be sure to have removed any nuts and washers first).
Then, screw on the shaft nuts (no need for the washers).
Connect the Enclosure Halves
Align the two halves and use the M2.5 x 6mm screws to fasten the base plate to the hex standoffs.
Knob Time
Place each knob over it's shaft and tighten the set screw to keep it secured. Make sure not to place the knob too low or the push button function won't work.
Note: if you find the set screw is bottoming out beyond the threading, add a small spacer such as a short length of zip tie plastic between the set screw and the flatted side of the shaft.
