VAOC diffuser assembly

VAOC body assembly

POM Spacer - OD9xID5.1x6mm

M4x8 Countersink Screw

Chicago bolt - female end

Spring - Stainless Steel - (OD6.35 L6.35) (0.51mm Wire Size)

2x M3x16 Cap Head Screw

Rat Rig Endstop - VAOC

VAOC body assembly

Please verify the fitment of both spacers, the nylon and POM ones, by attempting to insert the Chicago bolt through each while the spacer is installed on the printed part. Use the spacer that provides a sturdier and smoother experience when inserting the Chicago bolt.

This is due to tolerance fluctuations that Rat Rig is currently addressing. The initial kits will include both spacer options to ensure optimal performance.

POM Spacer - OD9xID5.1x6mm

Insert the spacer into the VAOC body assembly

Spring - Stainless Steel - (OD6.35 L6.35) (0.51mm Wire Size)

Chicago bolt - female end

Insert the Spring in the Chicago bolt - female end and gently insert them into the spacer. Keep pressure on the assembly for the next steps

M4x8 Countersink Screw

Tighten the countersink screw by fastening it to the female end, ensuring both ends are securely connected.

Test the movement of the Z endstop pin. It should move freely up and down and be consistently pushed upwards by the spring.

Insert two M3x16 Cap Head Screws in the designated holes.

Place the RatRig endstop on the assembly as shown.

Proceed with caution in the following steps to avoid dropping or losing the screws or the endstop.

Insert the diffusor into the VAOC body

VAOC CAM

5cm FPC

vc4_vaoc_midframe

Camera DSP PCB

2x M3x12 Cap Head Screws

Rat Rig VAOC LED module

Insert the VAOC CAM onto the diffuser, using the white mark as an orientation reference.

5cm FPC

Foam Strip - 1mm x 8mm - Adhesive 3M - EVA material, make sure to cut the foam to the exact size of your connector.

Carefully examine the 5cm FPC. The side where the text '3DO FPC - 5cm' ends indicates the VAOC CAM side. Additionally, there are numbers that correspond with those on the CAM.

Use the white dot for alignment.

Connect the 5cm FPC to the VAOC CAM module, ensuring the correct connector orientation. Align the small white dot on the FPC cable with the white dot on the VAOC CAM.

Rat Rig VAOC LED module

Carefully feed the 5cm FPC cable through the LED module, ensuring it remains connected to the VAOC CAM module.

Gently press the LED module down to secure it in the designated slot.

The LED module is a generic PCB and may have imperfections along its edges that could cause interference when inserting it into the slot. If you encounter any issues, use sandpaper to smooth and round the edges of the PCB.

If sanding the PCB is necessary, do so in a well-ventilated area, as PCB dust is hazardous to your health. Avoid inhaling the dust.

vc4_vaoc_midframe

Carefully feed the 5cm FPC cable through the vc4_vaoc_midframe, ensuring it remains connected to the VAOC CAM module
