This 3D model is a stand to be able to stack 2 of your Mako/Mahi iFixit driver kits on top of each other. This helps save space and is more convent. It is great if you don't have much room in a drawer or cabinet but it has depth. 

I suggest you print a model with a brim for more reliability and with the back support for the best outcome.

Note that none of the 3mf files have any recommended slicer configurations in them, please choose what is best for your printer

I am currently in the works of adding screw holes to the model so it can be screwed into something. I also am thinking about adding infinity or redesigning it to be compatible with HSW or MultiBoard. Please feel free to remix my model if you want to add anything to it that I haven't already.
