is it just me or are all three lengths the same in CURA see picture

Yep you are right, my bad!

Anyway, now I fixed it.


Printing this now to try the fit on my Geeetech A30. Looks like it should likely work as-is without any modifications. Assuming it works, would you be willing to add either a blank or a Geeetech logo knob to use instead of the anet text on the mk2 knob? Will be happy to post photos. :-)

Nevermind, please disregard the source request. Completely missed that the belt axis is rotated 90 degrees for anet apparently, so this didn't work for me after all.

If I will find some spare time, I will draw a version for the geetechn A30 with all the last upgrades used for my other CR-10 versions.

Hey, what do I do to prevent my printer from printing parts of the Screw model in midair? Using the MK2 Anet-A12-Y-Tensioner Screw model

That was my initial thoughts, but since you wrote that supports was only necessary for the Body model, I thought there was something else to it.

The nut and the screw don”t need supports...
What exactly is printing in middle air? Maybe you are using too thick layer, normally I print at 0,2 mm!
Post a pic, please!

The circled parts are being printed midair.

The screw was supposed to print in vertical.

Ok, it just loaded in like this.
You sure the print lines can handle the pull in that direction?

Built new design (MK2), the screw's diameter is a bit bigger. It fits tight to nut and it doesn't fit to body at all (some sanding can solve the issue I think). Can it be because I print them vertically?

The body is 24.5mm the screw is 24mm diameter, so should fit...is the same tolerance I used in the other tensioners (included previous versions).
I will try to print them to verify.
Generally I also print this in vertical, so...boh! Let me try check!

Probably my printer is not precise enough and needs some tuning. As you can see in the picture, the body is distorted...

So, after the print test, I understand where is the problem (and why in the CR-10 version the problem is not existing).
The thing is the acceleration/deceleration in the corners during the printing of the guides on the body and the screw. This is generating a kind of overextrusion in the corners that basically is going to reduce the clearance given in the drawings. The issue is not present in the CR-10 version due to the fact that the body is "open", so is possible a little of extra clearance.
Anyway, I improved a little the tolerances where needed (in my opinion).

I also attached a fitting test video.

I already noticed it, but anyway now I am printing the screw, the nut is already done and fit my others screws.
I will let you know!

Did you use PLA, PETG, or some other material? I love the design. I can't wait to print these.

Thanks for make this Y Axis Tensioner for the Anet E10/E12. I love the Design.
