After trying V2 out on a different brand of brass code 332 rail that is just a little tiny bit larger on the foot I found it was weakest on the spikes. They looked good but weren't up to the sliding onto the rail...which isn't a good start... So here's V3 with re-enforced spikes. I'm trying to have them look as prototypical as possible but strong enough for outdoors so there's always a compromise. On my Bambu Labs P1S it takes 55 minutes to print 50 of them. I am going to try resin as well.
I don't know how they'll go in an Australian summer !
