Designed to clip on to any of the 40g or less Aqueon tanks trim, or any tank trim that is 3/4" at the widest part of the trim profile.
Two hole design keeps the 1/4" OD air line tubing straight down into the tank or sump. I use these for dosing 2 part in a reef tank, unlike the commercial dosing line holders I can separate my lines by having them individually secured to the tank at separate locations.
This should work great for anyone who needs to secure 1/4" tubing, can be used for aquarium air lines, Co2 lines, 2 part, auto top off, etc.
I suggest printing at 100%, if you set a high number of walls I think that's a great way to achieve a solid part and ensure the printer is vibrating on diagonal infill and cut down print time.
I designed this in Fusion360. It's not a complicated part but it the 6th iteration of the design based on my testing. It has a small bevel to most of the edges to give it a nice feel and curved design to give strength where it counts.
