I received a old Printrbot Plus thru a program where i will donating it to a local school when I'm done upgrading it, I noticed some z wobble in the lead screws so i decided to create this brace for them. The upgrade should hopefully eliminate banding, I have not tested it yet but it should work in theory.

Assembly: screws 4 x M3-P0.5 x 35 mm 4 x M3 nuts
threaded rod you can use 10mm-1.5 or a 3/8" either one will work, just cut to fit.

you can print this twice, or mirror it on your build plate. I mirrored it so it would look cleaner on my printer.
