Description
This LM8UU holder is designed for minimal footprint on a laser cut Y carrier. The screws are captive under the LM8UU and since it is printed on its side, it's strong. It needs to be printed on its side so that you can force an LM8UU to be held by the part very tightly. The hole is undersized and it will require a bit of force in order to get your LM8UU to fit.
I modified this part because I keep my Y axis rods spaced quite far apart, and the same with my bed springs/screws. All of the other ones with "wings" crossed the path of my adjustment screws and I needed more clearance. Since I also mount my power supply under the front of the Y axis, so I couldn't fit the screws to tighten up the LM8UUs without hitting my power supply.

Instructions
I've included a chopped SVG which will help anyone laser cutting their own Y axis carrier with aligning the holes/outline of the part. The holes are made for 3mm screws, put the screw-head into the captive nut trap and fasten from the top of your Y carriage.
Don't try to snap in the LM8UU, it will probably break the part. Simply slide it into the hole while spreading the walls slightly. It'll be slightly difficult to get in there but not impossibly so. Once you've got it started, it should be easier to slide in. I printed my copies @ 20% infill, they were plenty strong.
The included SCAD isn't my own, but should be easily modifiable for LM6UU LM10UU LM12UU, etc...just remember to keep the hole a little undersized so it holds tightly.
