About this 3D model

I designed this because on my Dennerle Nano Cube the original hose clip of my Tunze Osmolator nano didn't fit without lifting the lid.So I made a thing which needs only 5mm clearance between the top and side glass.Just press fit the hose into the holder and fix it with a cable tie.if you are frightened of the hose may fall out, you can use a drop of hot glue to keep it there.Then use the screw to fix the assembly to the aquarium glass (max. 5.5mm) Use the holder_in for 0.25in hose and the holder_mm for the 6mm have fun :-)
