In the original design of this holder, the tool is held with the center of gravity much higher than the top of the model. This forced the top of the handle (as seen in the picture) to be unstable and tip outward (not shown in the picture). When added to a HSW to Multiboard adapter, it became too unstable for my wall.
I decided to alter the model so that the screwdriver would sit farther down and thus lowering the center of gravity to within the model itself. I also changed the connector out for a push fit connector for Multiboard. the result is seen below.
The author remixed this model.
The bottom of the cylinder has been removed so that the Milwaukee screwdriver sits with a lower center of gravity which, at least for my model, holds the tool more securely. Also, I removed the HSW connector from the model and added a push fit connector for the Multiboard wall.
