PZD Daisy Pod Groovebox Case

PZD-GROOVE-CASE: Professional enclosure for the Daisy Pod Groovebox designed by PZD.

A 3D-printable case for an Electrosmith Daisy Pod running the PZD Daisy Pod Groovebox firmware. It adds a 2.42" 128x64 OLED screen and turns the bare Pod into a self-contained instrument. The Pod's knobs, encoder, buttons, LEDs, audio jacks and USB all stay reachable.

The PZD Groovebox firmware (free and open source):
https://github.com/Peteranthony1st/PZD-Daisy-Pod-Groovebox

It's a four-layer tempo-synced looper with built-in synth engines:

Dexed: DX7-style FM
Ensemble: an organ/string machine
Grains: granular
SMPVO/SMPDR: a sampler with drum kits
Shared effects: reverb and delay
Each engine can be played over MIDI on its own channel, and you can save snapshots of all of them at once. The repo has full build and flashing instructions.

What you'll need
1 x Daisy Pod
1 x printed PZD-Groove-case (top, base, knob and 2 button caps)
1 x 2.42" 128x64 I2C OLED display module, SSD1309: https://a.aliexpress.com/_EQ1sEmm (Get the I2C version. The SPI version won't work with this wiring.)
4 x female-to-male jumper wires
8 x M2x6mm hex bolts
4 x M2 nuts
4 x M2 heat-set inserts (fitted with a soldering iron)
6 x 6mm silicone dots
Optional: 12-pin angled female headers, soldered to the Pod

Assembly
Inserts: use a soldering iron to press the 4 M2 heat-set inserts into the pillars on the top part until they're flush. Take care not to melt the case walls.

Mount the Pod: fix the Pod to the base with M2x6mm bolts and nuts. The bolts go in from underneath, and their heads should sit recessed. You don't need all four.

Wire the display: solder pin headers to the display and the angled female headers to the Pod. Then connect the jumper wires between the Pod and the display:

GND to GND
3V3 Digital to VCC
SDA to SDA
SCL to SCL
Then seat the display in its slot.

Buttons: put the button caps in their slots. Carefully lower the base on top, making sure the Pod's buttons line up with the caps.

Close up:

Bolts: fix the base to the top with the remaining 4 M2x6mm bolts.
Silicone dots: stick them into the 4 recesses on the base, as feet, and the 2 recesses on the top, over the LED holes.
Knob: push it onto the encoder, lining up the flat side as shown in the guide.
That's it.

A full illustrated guide, with screenshots of the print and support settings and photos of each step, is in the included PDF.

Firmware
To flash the groovebox firmware onto the Pod, follow Building and flashing in the README:

3D printing settings

Nozzle and layers: 0.4mm nozzle, 0.2mm layer height.
Printer: printed on a Bambu Lab A1 with the Cool Plate SuperTack build plate.
Orientation: use Lay on face on the top surface of the top, knob and buttons. Orient the top and base in the same direction.
Top and base supports: enable Tree (manual) with the Tree Slim style. Use the Support painting tool (Fill) to add support to the areas shown in purple in the PDF guide.
