Magnetic Camera Mount

I wanted a magnetic base for a wired backup camera to be used on a tractor while using a PTO stump grinder.  This is a preliminary print and does not address the attachment of camera to mount.  It will be updated once the camera is in hand. Drilled holes & screws may be used.  EDIT :  Printed a shroud for the camera. CA glued shroud to mount & used servo tape to secure camera to the shroud.  See pics.

The model uses a 25mm cup magnet, attached to the base by a flathead M3 screw.   The 20mm printed ball and collar is attached to the base using a M4 cap head screw and nut.  The camera mount clamp is assembled using M4 cap head screws.

The M4 screw through the ball makes for a sturdy attachment, reinforcing the part beyond the filament strength alone. Supports should not be necessary with appropriate model orientation.  I printed in ASA, but that is not a critical choice.

STEP and Fusion 360 source is provided as well as individual STL files.
