I had to modify the lens of my Toshiba projector. I printed out a 3mm spacer to put in the projector. I used the customizable cylinder on thingiverse (I can't draw), printed it out, sanded it into a square, and drilled the holes. It decreased the throw distance to about 10 inches.
I figured out how to mount the projector to a piece of plywood. Then mounted that to a 2x4 table I build. I ended up cutting a hole in the bottom of the piece of wood on the mendelmax 1.5 and then cut a hole in the table. It worked out pretty well.
I had a little trouble with the vat. I thought I would just sit it on the mendelmax frame, but it was to low. So I ended up cutting a couple of oak boards as spacers. I used some roofing rubber to give a little give to the vat to prevent it from breaking if the build platform goes to far. I'm just going to use clamps to hold the vat to the frame/oak board supports.
I printed out a mendelmax extruder platform I found on thingiverse with 4 bearings. (I had one with 3 bearings that was cracked). I also ended up printing a spacer under the platform to give me clearance of the sides of my vat. To get the spacer, I ended up using the thingiverse platform, and I scaled the Z axis to be huge in Cura (the X and the Y were not scaled). When I printed the part, I just stopped the print when it hit the height I needed. I also managed to get a piece of aluminum for the stage. I ended up epoxy'ing the platform, spacer, and aluminum together to get the final build platform.
I'll finish the coating on the vat soon. I have two vats, so I'll use Sylgard 184 on one, and the other one I'll try to get some release liner silicone coating.
