OX CNC Adjustable Foot

This is a CNC foot for an OX cnc machine. Using 1/4-20 nuts and bolts. the flange attaches to the outside corner to hold the foot in place. the foot sits inside of the frame. image 1 shows where the screws would attach it to the frame.
edit: updated to one hole in the correct place.

Edit: I've changed the design of the foot to sit directly under the extrusion. having the foot offset caused it to fail. it uses much more material but I think will last this time. I didn't include a way to attach them. If you find you really need to attach them; let me know and I'll make an edit.
