Really like the compact size, and printed the 5015 single pipe to use the close ABL mount. However, I recommend increasing shell wall count, and I'll be printing it again at angles to increase strength. Not a modeller yet, but would strengthen a few areas, and make some parts bigger. The channel for the wires are nice and clean, but too small. My wires push the fan out. I removed some of the tape (Ender3) to help.
A little arm on the left side of the wrap around pipe reaching up in to the guide channel of the base would be great to help support it better too (and screwed in).
Using it now! found water test worked really well. Needed a bit of hot glue to hold it together while I print another set. :)
