Worked perfectly ! Thanks for the share :)

On which orientation did you print the piece with No supports ?

This was extended away from the frame way too much for me on my Ender 3 Pro. No way I could even get it on without bending the screw. Maybe my Ender 3 Pro is a revised version. The bearing needs to come into the frame about 1/4 the diameter of the z screw.

This is for the Ender 3, not the Ender 3 Pro.

I had no problem installing stabilizer_v3 on my Seinsmart X Creality Ender 3 Pro, which I just received this month.

Any chance of support with none of the T type lugs so i can use on ENDER 2 ?

Hi, and thx for this: seems good.

I had some issues on my print (ender 3, Cura 4.2.1): strings inside the bearing location, and filament adhesion on the front.

Any idea?

I had the same issue with the same printer and slicer. But cutting the strings was enough to get it working (I didn't want to waste more PLA)

I had to reprint the knob once because the threads wore out from me taking it off and on too much.

Was hoping that I could use this instead of having to use the shim down below by the z motor but...alas....when affixing this to the top beam (even with raising it all the way up and then tightening it down) it jams up my z motor when it gets about 3/4 of the way up :( Thank you though !

did you try leaving the top loose until the assembly has been raised all the way up, then tightening it?

I've got 608 skateboard bearings in the mail for a spool holder and will have extras. Will these bearings fit this?

yup, should work fine

Unfortunetly it didn't work for me. It jammed my z axis motion. From about 8cm up it jams and doenst rise any higher. Had to take it down. Does anyone have a solution for this?
Thank you

You need to leave the screws loose, raise the x-axis all the way to the top, then tighten the screws down.

Ok, I'll try that. Thank you

Thank you. I wasn't sure if it needed to be inserted mid print or not.

Overall my print came out pretty good, only issue I had was the beginning overhand of the larger outside arc, seemed to have a little sag or not go super straight but after that layer it was fine and the rest looks great. Thanks.

Do you put the bearing in afterwards? Does it attach to a knob that's a separate stl document?

Sorry, I'll update the instructions, but the first thing you should do is insert the bearings into the printed stabilizer, then proceed to attaching the stabilizer to your printer.

The knob can be found in the "remixed from" section of this page

Do I need a new mount for the Z stepper motor in order to increase the height of the Z lead screw? Or this will work on a stock printer?
I?m asking this because my lead screw is not higher than the frame so I don't get how to screw the knob in....

It worked with my stock ender 3... the top is recessed for the z knob to fit into

Great! I haven't had the time yet to create this myself and add to my ZKNOB design. I'll definitely print one for my Ender 3 and add a link to it from the ZKNOB description if it works as expected.
