I am going to start my DIY sys cart build but while I work on a few other projects I wanted to design a drill/impact driver holder to fit in the label slot of the systainer. I designed one up for my M12 Impact and it works perfectly. Its a bit clunky but I kinda had to have as much support as possible as the slot is somewhat thin. I will be posting the design up in Thingiverse for those of you who have a 3D printer. I will also be working on a design to hold my M12 drill for the other side.
