This design is readapted to fit the pegboard mount that we have created so that i can hold different tools. 

We have 2 different version - exact scale as the original design and a 0.85x for smaller tools

Size 1x :  19 - 28mm

Size 0.85x : 16.5 - 24 mm

Based on many comments, do add something to increase the friction between the screws and your object. For me, I added a rubber band and it work very well
