Hey! This thing is still a Work in Progress.
Files, instructions, and other stuff might change!
2.5in 3-blade spinner
Description
This is another spinner. This just a bit under 2.5" diam (2.4375" to be exact). It is designed for a 9" x 6-7" 3 bladed prop.
Instructions
You will notice there are two versions of the base.
Version 1 of the base has an negative offset, meaning the bottom edge of the spinner will be "below" the prop adapter by .3125".
Version 2 has a normal offset of about .050".
The spinner cap is the same for both.
The cap and base are screwed together by M3x12-14mm socket head cap screws.
This should be pretty light, but I haven't had a chance to actually print this one out.

UPDATE: I printed out a set and installed it on a HobbyKing P-38 with a 8x6 prop (didn't have a 9in prop) and it fits nice.
