Garden Hose Roller Guide

A two piece garden hose roller guide with a print in place core.

Your printer should be reasonably well tuned so you get a nice friction fit between the spike and roller core. The roller to roller core gap of 0.3mm shouldn't be a problem.

You want supports on the pointed end of the spike. No other support is needed if you do the following.

When sliced at 0.2 layer heights use variable layers to print layers 56.6 - 62.0 at 0.1 height. If you don't you'll likely get a mess in this area as the outer perimeter will be a complete overhang. A larger nozzle may also help but I didn't try that. You could also print the entire roller at 0.1.

Let's see your makes!
