Issues getting Square Nuts into place... Help Plz????
I've gotten all the way to assembling the extruder head and I am completely stuck because of one square nut.
Every single printed part of my kit has been tight and the holes for square nuts are no exception. These cannot be inserted by hand. On the linear guides I went ahead and didn't use them in one spot. I'm hoping the single screws will hold it long enough I can get the thing up and running to print some new guides with a minor design mod that'll solve the problem.
I'm on the extruder head though I'm at step 16 of the X-Carriage and cannot get the last nut installed. It goes from the inside of a diameter towards the outside of the part and there's just no way to get the supplied pliers behind it to push in a way that works. Again this could be fixed with a minor design mod but right now I have to have it or else I can't continue.
Does anyone have suggestions for getting these nuts installed?

Square nuts are problematic, but an Exacto knife works to open a hole enough to make a nut fit. Even using a sharp screw driver like a chisel. But I'd not try running the printer with only half of something supported. You're just looking to bend something that can't be fixed.

Yeah just rebuilt mine for the MK3S upgrade and some of those slots were a PITA. I found using needle nose pliers to hold and push the nuts in worked in most places to get it started. Then I could get it pushed in though some were still tight.

Use the small allen keys to push most of the way in and then as a lever through the centre to pull straight.

+2 on an exacto knife. I have also used a small screwdriver and I small drill bit.

On a somewhat related note, I bought a bag of square 3mm nuts from Amazon, as I have used up all the spares. But the new ones are thicker than the ones Prusa supplies and don't fit in the slots!
