square anchor nut for eclipson pitts S12 and model R

prusaprinters

<p>I always get glue on the nuts that are included with the original eclipson pitts S12, that makes things suck pretty bad when you want to attach the wing to your model.&nbsp;</p><p>This is a version that will take a M3 square nut, no glue required, and pretty much guaranteed never to spin (unlinke the original). I think this should also fit the model R, but I haven't checked yet it it's the same size.</p>
