I really like this model and I am currently studying to become a Radiation Therapist. I made this couch to give additional DOF. Enjoy!

I made this to be compatible with the "floor" of this Linac visual aid. The basis of the remix design was from https://www.thingiverse.com/thing:1018097 but I modified it a lot via tinkercad. This is at full scale, but I printed my Linac and this at 50%. I glued the turntable to couch after installed in the floor. The "T" needed a bit of trimming and is glued to the "new table" I put a small screw in to stop the table w/ T from sliding out of the model.

No supports needed if you flip the couch vertically to print.
