2.5in 3-blade spinner
thingiverse
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.
