Radio Controlled Mark Ver 2 for RC Boat racing

This is Version 2 of a radio controlled mark for RC yacht racing. Version 1 was in wood and had problems so now on to a 3D printed version which is more accurately made and works well. At the venue we use we can not use boats, kayaks or paddleboards to lay are marks and they must be removed at the end of racing so these RC marks make life easier and also easy to move marks when the wind shifts.
Freecad Files available if required.

This version of the mark has now been superceded by the version 3 which can be printed on a 220 x 220 bed printer and has many other small improvements. Here is the Thingiverse link: https://www.thingiverse.com/thing:7102358
