By mounting my y endstop on the back rod, rather than on the y carriage rods, I was able to get another 5-10 mm of bed distance. Optional: uncomment the comments in front of the nut traps to print for use with non-nylock nuts.Thanks to triffid_hunter for uploading a parameterized endstop which was easy to modify. AFAIK this is the only parameterized endstop, the rest of ones on thingiverse are STLs.
