This is the screen block. Usually I try to refine blocky looking designs, but it looks fine and the 6028 fans are close to the edges anyway. Up to this moment, I was actually planning on using a 16mm hose to duct air over to the block, and this entire time I've been wondering hwo I'm going to deal with the hose when the block is closest to the side the hose enters into. I've instead gone with a dual 6028 solution.

I'd probably have to change it for something more secure, but for now I'm thinking of pushing in the 608 bearings into some channels. The white LED bars are the dual scanner sensors. I've heard that they're too fragile to take out of the plastic housing that they come in, so I've just left them as-is in the design.

I've also got to think about how the block with be attached to the X axis slider.

Hmmm and I would've gotten away with it too if it wasn't for that meddling plastic tab on the CIS. It's not like it would've helped much if it was ommitted anyway. I wont be suprised if the SuspenseSmall ends up being 605*605*305mm (H*L*D). Maybe small enough to put on a table or one of those "heavy duty" shelves on ebay, but relatively large compared to the print area. At least it should still compete well against the Photon M3 Max, which has a 9mm shorter X and 70mm longer Z axis.

[23:47] I just realised that since I've got scanner sensors on the screen block, I can actually remove the need for scanners between the application roller and screen block. That's £17 saved and 60mm of X footprint that can go to something else.
