These brackets are designed to hold the small Dewalt ToughCase+ accessory box. They will also work with the very similar Craftsman accessory boxes, but the fit is much tighter.
I’ve included a single STL file that has a 1″x1″ hole pattern on both the end and the back so it can be mounted flat or sideways.
Printer: Prusa i3 MK3
Material: Inland PET-G
Resolution: 0.3 mm with a 0.4mm nozzle
Wall Lines/Perimeters: 3
Infill: Minimum 10% Gyroid. The higher infill percentage the stronger the part.
Printing this can be a little finicky, I’ve noticed that the fit is looser with 2 perimeters than 3. If you are going to adjust the model or the print parameters, I’d wait an hour after the print is cooled.
