Hi,
I made new bottom part for RSCS vz235 to support 4028 fan mount. Fits perfectly to CNC bed support. 4028 generate much more air than 7530 and are easier to source.
You will need 4x 30mm m3 screws. No heat inserts.
Do not have to use supports, but I printed mine with supports.
Update 27/01/2024
added version with heat inserts - M3 4mm long.
The author remixed this model.
Changed default 7530 fan to server 4028 more powerful fan
