A parametric dihedral, useful as a replacement part or for building your own kite. The dimensions (i.e. 7.5mm) in the STL file names refer to the spar diameter for which it's intended; holes have been sized to fit such a spar, accounting for expected levels of hole shrinkage due to the printing process. The arm length, spine length and hole sizes can all be adjusted using Customizer; the spine and arm holes can be configured independently in case you're using a different diameter of spar for the spine.
Anycubic Kossel Linear Plus
Print with 100% infill for maximum strength, as strong wind may put a reasonable amount of force on it.
A vertical wall has been added to support the edge of the webbing, so no support material is required - which means that you should be able to simply take it off your printer and start using it!
