Inspired by dermatin's Low profile v-slot, designed from scratch (learning F360) to work with 2020 on my i3 knockoff.
Got carried away with designing and trying to print it fast, light, and use no supports. V4 required supports to get the holes to print right.

You can use supports on v4 and v5 for higher quality (at least from my settings) or print without. The droop I experienced was slight and didn't impact the use of the part. Better cooling fan on my machine will solve this.
