Helmet mount - no supports needed!

Most helmet mounts come with a lot of supports needed. This one prints without support.

Easiest way to assemble - turn mount 90° and assemble upper screw most way - then turn it down and assemble lower screw. Tighten both.

3mf includes more strength in wallplate - though most helmet weigh less than 1kg not much more than 20% infill needed.
