Mr. Holdy can be printed in 2 versions, medium with 3 perimeters and 10% infill for about 10-15kg stationary tool capacity, I use such for hanging my Stihl FS260 and FS55 and other garden tools and a sturdy version that prints about twice as long with 4 perimeters and 30% infill, its very hard to destroy, for me it is an overkill for regular use.
I print mine with orange PETG from Prusa so its little bendy under load and don't crack.
For montage i advice at least 2 screws, 3 if you want to be on safe side.
Happy printing
