I bought an Elegoo Saturn resin printer (wonderful!) but realized that some type of object are not as affordable as I would, because of ABS-like resin's bad habit to warp over time with small and thin items (I know, I know, really hard resins are on the market, but I can't afford their prices...).
Having time to spend I made this project, based on OpenSource project from Atom3D Proton, a very nice project, and strongly remixed.
The working plane is about 200x200mmx200mm, but you can customize all the stuff to your needs; mine is a standard heated bed 200x300mm with 12VDC heater.
I tried to keep the footprint as small as possible, 530mm all out left and right, 460mm height feet included, 500mm total lenght display and drag chain excluded.
Last but not least it'd be very silent and no flying wirings.
The 12mm aluminium tube contains all extruder an proximity sensor related cables.

Updates
- the LMK12LUU I received are bigger than expected, leaving no space for screws heads, so I made an 26mm hole (big enough to adjusting) at the center of both 4020 and inserted the LMK12LUU from below (see image)

Instructions
- Make 2 x 2.5mm holes at 180Β° on each LMK12LUU and tap them M3; use M3x12mm screws to hold firmly in place the two 12mm shafts.
- carefully check the perfect orthogonality of the three axes

READ CAREFULLY
Tolerances are tight (I use my Elegoo Saturn resin printer).
For FDM oprinters you'll have to modify where necessary all holes to apply your tolerance.
