RAM Mount X-Grip Foot
I Remixed the "RAM Mount X-Grip Foot by Radicalbiscuit "
( https://www.thingiverse.com/thing:2574481)
I found after I printed it the hole on the bottom wasn't wide enough and when I widened it out it wasn't deep enough so I made it wider & more deep. Works really well for the X-Mount I have.
I did find I had a lot of fail prints when I printed it with the smaller part on the bed, because it kept falling down usually right at the end when it was too top heavy, so I printed it with the fat part on the bottom with some supports to help keep it attached to the bed, required a bit of clean up but printed really well.
Printed on Creality Ender 3 V2.
