Workmate Vice Peg Grips

Here is my design to replace a broken vice peg for a B&D Workmate workbench.
My design is based on the original dimensions and works perfectly!

On the picture, you can see 2 new printed parts and one original (on the center).

Tips are welcome, it will encourage me to produce and publish new hardware hacks ... Thanks by advance!

This has been designed with FreeCAD, what a wonderful software ;-)

Printing tips:
I have printed the part in PLA.
Bottom, top and walls: 2mm
Infill: 50%
and it s very resistant!
