Anyone interested in this? It took me a while to get the design the way I wanted, but it works well now. I think I will sell the whole thing on Etsy, but also release the STL to buy somewhere as well.
Now on Etsy and MyMiniFactory

What are the straps like? Durability? And I guess the Etsy one comes with the straps then. You just strap this directly agaist yourself, similar to the hands2free designs?
The ones I use from etsy are the 1" extra thick nylon straps. Durability wise, I think they are slightly stronger than nylon straps you would see on a backpack. Yes it is meant to strap directly to yourself, which means it only works if you are of average size since it only works if the handy is directly next to your body.
