1 x HDMI to LVDS conversion board to drive LCD panel.

Connect 12V power and HDMI cables to driver board
(Optional) Wrap wire bundle in braided sleeve for neatness.

27Step 27
Attach one of two base plates
Fusion 360 object path: "Bottom"/"Bottom Left"
(Yes, the name can be confusing. We're building the chassis with the front facing away from us, while the CAD was designed while looking at the front, so the left/right names are flipped from what we are seeing now.)
Tap 6-32 threads as indicated by two blue circles.
2 x M5 10mm socket head screw
2 x Misumi HNTT5-5 extrusion assembly nut
-
28Step 28
Continue building the chassis base

2 x M5 10mm socket head screw

Two of the nuts are used to attach the base plate to the extrusion. The third nut is added to the opposite rail (facing away from the camera in this picture) for later use.
