This is a simple hook that allows you to attach various items to the sides of pet cages (accessories, toys, etc.).
Few different lengths of the arm are provided, but please feel free to rescale/remix if you need different sizes. The length of the horizontal part has been designed to fit between the bars for installation, and then rest on 4 different bars to divide the load evenly.
Those are designed to perfectly fit on the bars of small pet cages with 0.5 inch spacing (which is standard for smaller pets, like hamsters, gerbils, guinea pigs, ferrets, etc.).
For more interesting projects, please visit my blog:
Print laying flat on the bed, no supports needed.
Use higher infill for more strength.
You can also make them thicker, if desired.
Just try to avoid scaling it height-wise, as this may cause it to no longer fit between the cage bars.
Those are strong enough to mount some accessories (inside or outside the cage). I designed them while working on an IoT hamster wheel tracker, to mount the complete device outside of the cage (see my blog for more details: http://www.BogdanBerg.com/).
