On the down side, if you ever try and hold an acrylic nut in your hand and thread it you will see how much force it takes. I threaded about 30 of them and my hands were pretty tired.
So I decided to go with oval nuts and see how that works out.
I made a jig for threading them. I’ll report back on how good this works. I should be assembling a few gondolas over the next few days (and other parts using this fastening technique).
