Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This is another flying toy project I wanted to get to for a long time.
With a pull of the ripcord, you can launch propeller rings (or spinners as I call them) nearly 30 ft high or more than that horizontally.
You will need:
* 2 608 bearings (not included)
* 1 axle
* 1 gear
* 1 base
* 1 handle
* 1 or more spinners
The spinner naming convention is:
* bld = blade
* spr = spinner (or propeller ring or disk or whatever)
* w = width
* d = degree (for angle of attack)
* h = height
The spinners I have posted are the ones that performed the best based on my testing.
***UPDATE*** I'm experimenting with twisted blade spinners and have just posted a couple: 3 bld spr 120w 55d-20d 8h v3.stl and 3 bld spr 120w 55d-10d 8h v3.stl Both fly awesome and I believe may be better than the flat blades, which was the hope (less drag)
Want to make your own spinner??? Please do and post it! I posted a STEP file template so you can create your own. I can't wait to see what you come up with
<em>CAUTION: Eye protection recommended: These are thin, 3D printed parts, most likely printed with a brittle plastic, which spin at high speed. I have had a couple spinners shatter on launch. Happily, there were no injuries when this happened and since the spinner parts are very light, I think injury is unlikely, but it is better to be safe than sorry. Also, don't use a ripcord if the stop tab breaks off, since it increases the chance of causing too much initial force on the…
