I modified barty3d's Ryobi tool holder to fit Biltema pegboard. This one is a bit tight for some tools but perfect for some.
Oleost has better toolholder for some tools and it uses less plactic, but for example Ryobi P755 fits much better to this one. Don't resize this or your screw holes are not aligned anymore. Just print one of this and one of Oleost's holder and try your tools on them to see which holder you need to print more copies. No one has just one Ryobi tool, am I right?
Some tools like power drills are too heavy for these holder.
