3D printed barbed connector

[sepi]

Hello everyone! I've had the idea floating in my head for quite a while to make my own barbed connectors/fittings for connecting tubing as used in the dev kit. I finally got around printing a series of prototypes in PLA. The results are promising, even if the value of printed ones is questionable. Designed them so that you print them lying flat in order to optimise lengthwise strength. To get them watertight, you just need to sand the barbs a tiny bit.

I have two main reasons to print these parts myself, first of all, I forgot to order them and secondly, the more parts of the dev kot can be printed, the less people will have difficulties sourcing them.

I'll publish a Freecad file once I have it tested and printed in PP.

The raw part.

Awesome, nice work! These fittings normally come with the pumps I think? But I don't know if we specify them in the docs directly. Definitely good to have this as a backup/short-term solution!

My pumps didn't have them, only the ones built into the pump. I saw that on some of your pictures, you have additional fittings between the different elements, I guess to make it easier to connect and disconnect the cell. In the end, it might make more sense to just shrink the barbs on the flowframe and/or tank a bit so the tubing comes off mor easily.
