Gridfinity / GridZinity vertical pegboard hooks

These hooks snap on to the back of standard gridfinity bins, in heights 2u, 3u, 4u, 5u, 6u, 9u and 12u, with space for the stackable lip. Please note that the lip is required - it's the mechanism that allows the hook to grab the bin. They can then be attached to pegboard with round holes. The hooks are smaller than necessary for ¼" pegboard holes, but I've not had any fall out. 

They click into the stackable rim at the top, and also align with the base at the bottom. No problem with a reasonable amount of weight (see the (badly printed) battery holder for example).

Here's a link to the OnShape model that I used to create them. If you want different depths, or a thicker hook, please feel free to modify.

I printed them with a 0.6mm nozzle on my Voxelab Aquila, but a 0.4 nozzle will be at least as good, and maybe better in terms of capturing detail. They print lying down, without supports, and at least in my case they don't need a brim.
