Mast mount (starboard tack) for Jan Heylen's DIY GPS

This is mast mount for Jan Heynen's DIY GPS. https://www.seabreeze.com.au/forums/Windsurfing/Gps/Another-DIY-GPS-logger-approach?page=1  

Not my idea (Boz's) and (Al Hop's integrated elastic strap) but aims to put display more in peripheral vision. This is because during a speed run or choppy conditions it is very risky to glance at the boom mounted gps.  The shoulder GPS is in peripheral vision but requires changing focus which is slower and probably more dangerous than glancing at boom.

This print is designed for the BE-180 (M10) GPS and is plug and play (as much as possible), meaning you can plug in any Universal Qi Wireless Charger Receiver and not have to extend cables so only 6 solder connections (4 for GPS and 2 for reed switch + 2 for the extra reed switch if you keen).   This print is for Starboard tack as almost all speed runs in southern hemisphere are weirdly Starboard.  

From just one session it appears best location for this is bottom of sail cutout. (Your preference may be different).  Originally I thought would need to make a Port version but seems an easier/better solution is a flip system, either manumatic depending on your location or possibly automatic using the sail/cams to flip the display each tack.  This way, one would only need to build one GPS so cheaper, easier entry to the sport etc

(Note the ‘centre trim’ is for those brave enough to do Al Hop's peeling of the epaper display from the PCB and recentering to give more aesthetic look)

For the mount I used elastic shock cord from local hardware store which was about 4mm diameter.

Please note, this print is not waterproof as printed.  You need to fill with potting epoxy through the fill holes. Please see previous/initial design for more tips on how to do this.

It was designed for RDM masts, it may work for SDM but haven't tested it.
