Parametric mast mount for MeshCore enclosure – FreeCAD

Parametric mast mount bracket for IP67 boxes, MeshCore/Meshtastic nodes, and outdoor electronic enclosures. 
Designed in FreeCAD, this 3D printable mount allows easy attachment of a waterproof enclosure to a mast or pole using standard mast fasteners (58 mm center-to-center spacing).
Compatible with many outdoor projects.

All holes are designed for M6 (6.4 tolerance).
default enclosure size : 150x150x90mm 
Adaptater size : 108x158x8mm

Most IP67 boxes have dimensions written on the back of the enclosure.

The model can be customized directly in FreeCAD through the first and second sketches used by the pad operations : look at the rectangle dimensions in the first sketch.

Future versions may move parameters to a global spreadsheet for easier editing.
