Here is a visor for the Garmin Striker 5CV Plus Sounder/Fish Finder.
Its a very simple print with no supports at all needed. Its a fairly long print though, at around 18 hours. (0.2mm @ 50mm/s)
Print with at least 4 perimeters. There is very little infill, but use at least 50% for some extra rigidity.
4x M4 x 6mm Stainless Steel screws are recommended. (5mm would be ok) (The mounting backing is 2.5mm thick and the Striker Plus holes are 4.8mm deep)
If you download and like this design, give me a heart!
Enjoy and tight lines!
