This is a basic wall mount for a DeWalt jigsaw (DCS331). Its designed to be quite snug so that the tool doesn't slid out if you want to mount it under a shelf.
I printed it with 6 perimeters and %40 infill as I wasn't sure how strong it would need to be. You could probably get away with 3 perimeters and %20 infill as mine is definitely overkill strength wise.
The author marked this model as their own original creation.
