A jig to cut a sear sleeve from a common 1/4"ID x 3/8"OD x 1/2" length solid machine bushing to insert into the frame of the Big-Point. I found these bushings at my local small town hardware store at low cost. I cut the slots out with a grinding wheel on a Dremel. It may also fit the Lo-Point, but I don't have one to try it on. Prevents the sear from binding in the plastic due to the tremendous side loading of the trigger system. You can drill your frame with a 3/8" bit and install it, Or please feel free to add this cavity directly to your models before printing. Also, you can use this as a test print for sizing before you print the whole frame. Now uploaded in .stl format

If you find your trigger function sucks hard, look into do the steel insert for the sear, like the factory frames have. Look at "Big-Point's sear saver" on the sea. It helps, but it's still designed by Hi-point.
