NZAK Simplex Multiple size cylinders and 1 ribber
thingiverse
UPDATE - added multiple cylinder sizes but beware i have only printed the 72. i would imagine your printer would need to be really accurate to print any higher cylinder size than that. i edited wbtextile's https://www.thingiverse.com/thing:3326079 file to make the needle slots 1.45 instead of 1.35. with 12 gauge needles there is not enough room for the needles to slide freely. it works on my 2006 NZAK Simplex machine. i have not done the ribber yet, but planning too. This Design is not my own, it is just an edit and i do not take credit for wbtextile's work, i am just offering an edit to her file for the bigger slots. Thank you wbtextile for all your hard work so that i could make my own cylinder.
