Dalprop folding propellers - Adapter for T-Mount motors - 2-blade conversion

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4873347.

These adapter allow mounting the 5-7" Dalprop folding propellers to T-Mount motors. They also allow converting these propellers from a 3-blade version to a lighter 2-blade version.

I tested this on an ultralight 7" longrange setup with Brotherhobby 2004 motors on 2s and it was working well.

With higher cell batteries they might break, as 3d-prints are less robust than injection molded polymers. However i'm pretty sure that up tp 4s should work just fine. Especially with the 3-blade-version, as it uses the injection molded stock upper part.

If you try them out, please share your experience in the comments. This would be much appreciated!
