Requirements:
Extended handguard
Extra screws to mount rails
At least ~220x220mm build volume, the top rail when rotated 45 degrees is ~213x213mm
The bottom rail also covers the bottom of the receiver, so go to my other model if you don't want that.
Edit 2/22/26: Just realized there was a 0.1mm gap in the bottom rail, fixed that.
The author remixed this model.
