What software are you using for modelling?

Also, is that the spinner they "tested" in the recent video? I've experimented with printed spinners in the past. I probably over-designed them and had trouble with balance instead of material failure.

If so, do you have more information about how/where they are failing?

I use Autodesk Inventor and Fusion 360. The spinner was done in Inventor (mostly because I am more familiar/comfortable with it, 15+ years).

The spinner they exploded in the VLOG was a previous version. I also think that the print settings and material they are printing with are contributing factors. I flew the latest version of the spinner over the weekend on the C Pack with 3S and 4S (9x6 APC prop) with no issue. I will be posting the file on Thingiverse very soon.

Also, all my testing has been done with PLA. ABS and PET-G are probably much better suited for this application. I hope to test those in the future. Full disclosure. I am by no means and expert in 3D printing. I've only had my printer for a couple of months now and I still have a lot to learn. The spinner was been a really challenging and fun project to work on and I am grateful to Josh Bixler for giving me the challenge.

Personally, I think PLA is a good choice. ABS would be tricky to print and probably have poor layer adhesion. PETG has awful impact strength which would cause some interesting situations on rough landings.

Really, either PLA or Alloy 910 nylon. I worry the printed nylon might be too flexible. PLA gets a bad reputation for being the trinket material, but it can be printed for strength and has a good place for "engineering" applications.

I think you may be confusing PETG with PET. Impact strength and toughness of PETG is very high, and layer adhesion is way up there as well.

Nylon would be too flexible for a spinner I'm thinking. It would bulge out a lot under centrifugal force.

Question

Added the MiG-3 Exhaust.
Sponz, do you have any opinion and/or insight on the many FT parts that are on the Thingiverse site? I know your Pietenpol engine is there but there are also many iterations of engine firewalls and control horns, among other things. Just curious, as I don't want to waste time and filament trying to print something that's not worth the effort. (My Prusa i3 MK2S kit shipped today from Prague. Yay!) Thanks.

Question on 3D Spinner on Thingiverse

Hi SP0NZ,

Your Thingiverse STL is in a single file, Is it possible to separate the files into 2 different STLs for smaller printers that can not handle it in a single print?

Awesome Design cant wait to try it!
Thanks!

Sp0nz,

Are you going to post the mini camera tail mount you made?

I saw it on one of the models at FFW, I think it was either the Mustang or Mig.


I love that video and definitely want to do the 3rd person FPV with my soon to be completed FT Sportster.

Added the FT Gremlin Frame design by TJ Wiliams on Thingiverse. Link is the first post. This is the first of many FT Gremlin frames that will be added in the near future.
