SSR90 hop presser

thingiverse

These are hop pressers for the SSR90 hop chamber. They should fit snugly (if not, play with horizontal expansion in Cura or the equivalent setting in your slicer of choice), and only having a single contact point with the wheel, both design features eliminate canting of the presser, and thus eliminate the tendency of having shots curving left or right.There are 3 designs: A curved one (10mm radius), a flat one, and one with a recess for an omega nub.I've used a 0.2mm nozzle and very slow print speeds to get this printed in PLA. Again, the trick here is adjusting the horizontal expansion to your printer tolerances, in order to produce a part that fits snugly into the hop up chamber.
