3/4" PVC Spike

thingiverse

Spike slips snugly into a 3/4-inch SCH40 PVC pipe. The tapered connection ensures a tight fit, and the raised ridges on the print make it stick firmly in place without glue. Inside, a hollowed dome provides added strength at the top while minimizing plastic usage. A dowel can even be inserted for further versatility. At a 1.0 scale setting on my Monoprice Mini Delta, Spike was slightly too small to fit, so I adjusted the scale to 1.04, but next time I'll opt for 1.03 to achieve an even tighter fit.
