3D Printable Makerslide Actuator mount

This is an attempt at a 3d printable actuator using makerslide and .5in acme rod. I saw a part where a washer was used as the metal contact point for the eccentric spacer. Using this idea and some parts I had around I started designing this. I have no idea if it works as I do not have the bearings for the end bearing mounts, but am still working on it. Right now the printable sleeve for the nut almost works. There is a bit too much flex for the v wheels to line up on the rails when tightening. I did have a pretty low infil while testing the design and will print with a stronger infil to test. If anyone has any ideas please feel free to let me know. If I can get it working better I will make some parts that have more than a makerslide mount.

Right now it uses a 1/4" SAE for the internal 9/32" diameter to spin the eccentric spacer. The other v wheel mounts are stationary and just use 5mm washers. The eccentric spacer side uses 1 30mm m5 bolt and the other 2 use 25mm m5 bolts.
