Great bracket best one I've seen, clips on nice and tight.

I modified the bolt and bearing to be 100% 3D printable no bolt, nut and bearing required.

Easy print
Printed on Ender 3
No supports required
4mm brim
0.3mm layer height
infill 15%

The pockets for nut and bolt could do with being a tiny bit bigger. About 0.25mm or so to the radius. Everything else is great.

Any chance you could make one that mounts on the leadscrew nut screws? It would be useful for anyone running stepper dampers, as the x motor rear damper bracket occupies that space and can't be relocated

this thing works great thank you

This is great! also, I was able to use the printed bearings and they work just fine for this application! can be found here https://www.thingiverse.com/thing:2747989

608 bearings

Commenting this just so I can find it later ;)

You should check out this store (https://goo.gl/gCxmH6), although the bearing in the picture is an open-raceway ABEC-9 (I know it's overkill I just happened to buy a stack of them when spinners were still a thing...)

can you clarify a couple things?

"The bracket can be printed with 3 outlines, I designed it for 0.5mm extrusion width."

3 outlines?
.5mm extrusion width, doesn't the width have to match the nozzle size or less?

thanks

On the contrary, I recommend the nominal extrusion width should be slightly larger than the nozzle size... This makes the cross-section of the extrusion oblong, allowing for a better bond between layers. If you don't believe me, give it a shot. Three outlines makes a shell 1.5mm thick, which should be plenty.

i'm just getting started so i'll take every piece of advise i can get. when you say 3 outlines, 1.5mm thickness, .5 extrusion width, I think that would mean i set "Wall Line Count" to 3 in cura and outlines is a term another slicer is using.

That sounds right! Send me a message if you're still having trouble, I'm not super familiar with Cura but I'm happy to help
