I was asked by my nephew to help mount a rudder on his Lifetime Yukon kayak. The stern is not flat and has no built in mount point. Working with the bracket he ordered from Amazon I made measurements to design a shim in Blender that would set the bracket flush to the stern. The bracket and shim will be attached with 1/4 x 20 stainless steel bolts to well nuts (expansion nuts) placed inside the hull.
Printing:
Having recently acquired my printer, I only have PLA and PETG filament on hand. I chose to print with PETG due to the constant exposure to water. Most of the Cura settings were left at default, unless I have changed then and forgotten. The infill is fairly low at 20% but bulked up with the line multiplier of 2. When permanently mounted I will assess and test to see if I must reprint at higher infill.
Full print with 2x4x4 walls/top/bottom and 20% infil came to about 4g in weight.
