I finished a mast mount that is customizable without any commercial CAD programs necessary: 6384 mast mount for efoil or foil assist (parametric / customizable to any mast) by rekliner - Thingiverse
It’s only for the 6384 for now but I’ll get the option for 65161 uploaded soon.
This is for those of you that can’t find 3d prints to fit their mast and don’t want to buy or use a cad program. OpenScad is not what anyone would call user friendly, but if you can work with code then no CAD skills are needed…nor is any money, its FOSS.
If foilers find this useful and care to contribute mast measurements I could set them up as defaults to make for easy printing. For now it’s only my go-foil mast and a generic template.
