I won't rate this. I've printed it multiple ways, support, no support, every way possible. There are gaps in the layers. A gap that runs on both sides of the tube and the cross support. I think this would be better if it were an arch that holds and supports PTFE tubing. I'll try again later, but I didn't want to give it a bad star rating. I don't know how you printed it but if you want to share that'd be great.
