You need a 3d printer with a large print volume, this was designed to fit
on the Ultimaker, but I believe the Replicator should be capable as well.
Total cost of all parts comes to around $450 (see BOM below)
- download the .stl files provided here and print them out
while waiting for the prints, order parts needed from the following BOM
this is going to be a bit of a work in progress, I am working on a
complete build log, with step by step instructions, might be a week
or 2 before it's complete, check back!
(the exploded view photo here should give you an idea how the pieces fit)
- follow progress on my build at the mtbs3d.com forums.
the zip file contains the gerber files needed to make an LVDS -> HDMI
breakout board, just send the zip to a place like itead studio etc.
or etch your own.
- you need to print 2 of the RA_HELMET_MOUNT.stl, the 2nd one should be mirrored
There are 2 "Lens Plates" in this design, one for a LEEP optics variant for the 120+ deg fov, and another that uses 50mm lenses, that give you a 90+ deg fov. the choice is yours, if you do use the LEEP optics, read the notes below regarding the lens grinding jig.
- if you printing the leep lens holders for grinding the lens edges, you need to do the same, print 2 of each and mirror the 2nd one, for left/right lenses.
the holders are used to clamp the large lens of the 2 lens set, you then use a belt sander to grind the edges down till they are flush with the printed jig. simple..
