Step 1: Parts
2X: 3x4 plate with connection brackets and 1x4 plate with opposite connections (as seen in 1st picture)
3X: Antennae(I used some spare ones from old remote controls)
1X: Bolt(as seen in 2nd picture) that will can screw into the camera to hold it into place(fiddle around, I found mine in a spare parts bin)
1X: Piece of metal used for structural stability(optional)
1X: Piece of metal or dime for twisting the bolt to tighten the camera attachment
As you can see, the only way to classify parts is as either Lego or Non-Lego.
All Non-Lego parts can be, with some difficulty, replaced with custom or store bought parts.
Total Cost-$0 (may be up to a dollar if you don't have certain parts)
