Petzl Vertex helmet basic mounting plate (also for customisation)

I was looking for a solution for mounting stuff to my new Petzl Vertex Vent helmet, in particular it was the battery pack of my headlamp. So i found KIL0's design, which seemed quite sturdy, i printed it and was very satisfied. Unfortunately he did not provide the CAD files, so I redraw the interface surface to his adaptor brackets and extruded an even surface for a velcro strap, because my battery already had a velcro strap.

You need the following hardware

• 4x M3 nuts
• 4x M3x12 counter sunk hex screws

Instructions

• Print both adapters and the body
• Insert nuts into the body
• Screw brackets to body

Tipps for your own design

• The brackets take up approx. 5mm of the screws' length
• An ordinary M3 nut is 2.4mm thick
• You can use my reverse engineered drawing by importing the DXF file or use my Fusion project as a base for your design.
