5.5-mm Nut Driver

prusaprinters

Sometimes you need a nut driver for 5.5-mm nuts, and you just have to make it yourself!Layer height, fill percentage and material are flexible. Image shown is 50% fill ASA with 0.2mm layer height. The printed example is also from before I added the hole. Printed on a Prusa i3 Mk2S. There is a fair amount of face on the nut driver so a brim is not necessary.Finished size is 31.2-mm tall and 22.2-mm wideWorks best with materials that print true-to-size like PETG and ASA. ABS needs some scaling to fit on the nut.The inside does not need support as it is made to be  45° overhang. The ears of the tab print better with support, as does the hole in the tab, bit it is not strictly required.It fits snugly on a 5.5-mm nut when printed in ASA which maximizes how long it will work before the nuts tear it up.
