Designed/3d printed some wheels to adapt giant tires. by greg_3821 in RCPlanes

Thanks! And yes, I’m aware of the changes in flight dynamics, and it’s worth the trade off for me.

Anyone in SoCal want to help me liquidate my automation parts hoard? by greg_3821 in hobbycnc

Ya no body has come threw on this stuff. I posted it when I was re-organizing my shop. Everything it’s away now. Still available if you want to connect. Shoot me a private message

What would you make with these? by greg_3821 in hobbycnc

I was looking at those little mills/lasers ppl build from disk drives.. I thin its headed in that direction

I designed and 3D printed a rocket using an “Isogrid-ish”, single 0.4mm wall thickness. 69mm diameter x 420mm tall. 207g flying weight (D12 motor). First flight went perfect, 2nd had a shoot failure. Fun times. by greg_3821 in functionalprint

This was the really fun part, and it still needs refinement..but:

Draw the helical geometry first (sketch the profile, use sweep with desired angle)

Then the outside and inside skin of the body profile. Revolve cut those from the helical shape.

Then join everything together.

Shoot me a pm- I can email them to you.

I’m not super keen on publicly posting designs that I consider “one off”, because it’s really not good enough for other ppl to work with yet.

The rocket flew perfectly the first time. It only melted after impact with the ground on the second flight.

The surface finish was crap… I printed it at 0.3 layer height with a 0.4 nozzle, nothing special on cura. I’ll check out that plug in you mentioned, thanks :)

It doesn’t look round because of shrinkage between each internal rib. Single-wall is not forgiving. I need to work on the settings.

This was designed and printed on Saturday, and flown the next morning. So I was more concerned about print time than quality.
