chuni-lite

kinda cheap slidy air towers for an arcade chuni slider.

• 3D printed parts + a mirrored set
• USB C cable
• Hot Glue

Can hand wire, or replace air_tower_top_1 3D print with chunair pcb. chunair_core PCB also optional, but is there for ease of wiring(might need to find a way to secure the pro micro as well)

Basic steps: 0. Wire up your slider's 12v and DB9.

1. Print parts. Then print a mirrored set.
2. Assemble parts with hinge.
3. Glue leds/pds if you are using air_tower_top_1. Wire according to the diagram in "ac chuni/wiring.png". If you have PCB, solder resistors and leds/pds
4. Shove unsoldered end of ribbon cable through the channel.
5. Solder to Pro Micro or chunair_core pcb depending on what you have
6. Thread M4 screws through rubber foot and slider to mount to slider.
7. Mount DB9, 12v, and pro micro to mounting plate
8. Unscrew the two m4 screws and add mounting plate with those screws
