NotFastEnuf "Boss Series" Brushed Frames - 3D Printable (v2 stl files post #368)


Has anyone tried Esun’s CF/Nylon?


I do have a bit of an issue with printing XL 7 mm frame. As shown with red arrows below there are some gaps which in my opinion shouldn’t be there at all :frowning:
Any clues ?
Btw. I’m using M3D Micro printer along with the newest Octopi software.


Slice it with cura.


I see the same issue if I try to import it into, say, Tinkercad.
Sliced in Cura it’s fine.


Any idea why it breaks? I’d love to tinker with it in Tinkercad - but can’t…

I think I need to make the motor holders about .2 - .4 mm thicker to make an indestructible PC print…


I’ve designed a brushed frame inspired by the Boss.
Main reasons were to have a frame that works well in PC.

With PC or seems you can keep strength and stiffness with thinner arms, but the motor holders do need to be a bit thicker.

This design is super stiff in PC and about 1/2 gram lighter than a Boss XL on the same footprint.

Seems to fly well and has survived several big crashes into my kids climbing frame unscathed.

If anyone is interested I’ll post the stl.


Which motors are those?
