This is designed to work with the WHS which I have uploaded as well. You can use supports to print this if you want but my admittedly heavily modified ender3 printed the prototype and it's been in use for 9 months with no issues.

The prototype in the images was printed in pla but usually, for anything that will see regular use/impacts, I recommend PETG but that's also because PETG is my fav material. You might have your own material affinities in which case - you use what you feel comfortable with.
