I did a remix for a M12 tool clip, how ever that clip system was no match for the M12 palm nailer! So I set upon designing my own Tool clip for Heavier M12 tolls.
The Tool Holder is designed to stick out from the tool the same distance as the normal battery would. In the case of this palm nailer it uses the battery to help it stand up and rest on its other support. Has a countersunk screw hole near the bottom so you only need a short screw.
I used the canvas feature in fusion 360 to get the basic shape of the battery, then just extrapolated from there. not bad for my first spline project.
I want to add some spring loaded clips for added security at some stage, so I'll upload that when I'm done.
