Yes. At the time I printed the mount, Cura did not support custom supports; it only supported support blockers. I needed to turn on supports everywhere and then block supports for all blind holes and the wire tunnel for the endstop. That basically left generated supports for the endstop mounts and the cooling fan tunnel. Now with CURA, you should be able to keep Generate Supports off and apply custom supports to those areas. Other than that, I printed in PETG with a brim to prevent any warping. With ABS you will probably need to do the same with the addition of a heated enclosure of some sort. When I printed ABS parts on my Kossel Delta I tented it with a garbage bag. The temperature under the bag reached 104 degrees F. and allowed me to print without warping.

My delta has a bottom enclosure that lowers the electronics away from the heated bed and includes drawing outside air for cooling. The tent did not cover the PWS or the cooling air intake or exhaust ports. The heat did cause the PTFE tube in the hot end to cook and I had to replace it; but it lasted long enough to print my parts.

Good luck.
