Slide the hud-power.stl part over the power circuit and snap one of the ends to the hud-bridge.stl piece. Neatly tuck the extra wire slack in the hud-power.stl part without kinking the wire wrap.
You'll need to unsolder the four connections from the power circuit in order to increase the lengths of the wires.
Use a third-helping hand to hold the wire bundle in place while you tin them. Measure about 135 mm (5.3 inches) of 30AWG wire wrap in length and solder them to the ends of each wire. Use shrink tubing to secure the connections.
Make sure all the components are disconnected before putting them into the enclosure
Place the plastic eye piece with the magnifying lens on top of the hud-eye.stl part. Reuse the same screws and use a screwdriver to secure the eye piece into the hud-eye.stl part.
Position the eye piece into the hud-cap.stl part with the ridden and cable connections threading through the opening in the side.
Get the hud-elbow.stl part handy and carefully thread the wire connections of the video eye display through the cavity. Snap the hud-elbow.stl part into place.
The hud-kopincap.stl part needs to be inserted to the hud-elbow.stl end with the cavity facing away from the eye piece. Set aside the eye display for now.
Grab the extended wire bundle of the power circuit and thread it through the hud-bridge.stl and the hud-kopin.stl parts. Ensure the hud-bridge.stl part is threaded first and positioned with the end capable of snapping into the hud-kopin.stl part.
Get the micro Kopin in position and connect the extended wire bundle back to center port. Ensure its oriented properly!
Position the micro Kopin towards the eye display piece with the ports facing inwards. Carefully reconnect the ribbon and ported cable to the micro Kopin.
Gently slide the hud-kopin.stl part over the micro Kopin and tuck the wire bundle through the enclosure. Position hud-kopin.stl part close to the hud-kopincap.stl part with the clip piece facing inwards and snap it into place with.
Align up the holes on the hud-cover.stl part over the power circuit and snap it into place. You may need to insert the USB cable through the hud-cover.stl part, connect it to the power circuit, and then snap it onto the hud-power.stl part.
