On reading the comments from the original it appeared the screw holes were being reported as to small. https://www.prusaprinters.org/prints/55082-universal-cordless-drill-hanger So before printing I added an extra screw hole and increased the original 2 holes to 4mm
This was very sturdy when mounted. However as I was mounting a slightly larger cordless drill, the picture shows a piece of ply mounted behind to make a better fit.
Therefore there are 4 prints. 2 copies of the original but with the extra and larger screw holes, Left or right facing. The other 2 are copies of this but 3.5mm thicker base rather than getting the plywood out as I had 2 to mount.
The author remixed this model.
Larger screw holes left and right facing, thicker base
