The holder ensures that the hose does not kink and protects the material. Have the parts themselves in use (Bestway Steel pro) and am very satisfied.
The connectors are screwed to the standard pool connections.At the inlet you can now connect with the various put on, skimmer or pool cleaner. Tip: use the connector with Ø41mm for the Bestway skimmer.
The outlet improves the flow in the pool and improves the performance of the skimmer.
Have fun with it.
I have designed the holder so that you do not need support. I recommend an infill of 8% (line pattern) and at least three wall lines. Can be printed at 50mm/s without problems. Part weight 120g, printing time approx. 11h.
The hose connectors should be printed only with wall lines.
The threads without support!
