to be clear, this
>>3798401 is what the scan here
>>3798333 looks like when that metal spring/coaster is removed, and you add a negative.
the lip in the attached pic is what is causing the white stripe on the top here >3798401
it takes an annoying amount of disassembly to get the plastic piece off and i dont have time for it right now so that's all for now folks.

It would be pretty straightforward to design and 3d print wider coasters that would accommodate 6x7 or even 4x5. With that you can scan:
> 6x7 frame in 6 runs (result is just under 84 true megapixels)> 4x5 frame in 20 really arduous runs lmaoIf you could design a cameradactyl-type autofeeder you could scan
> A roll of 120 film in 3 runs> A 4x5 sheet in 5 runs
