For me it is one of the best(because I made it):D improvements what you can get to improve your stiffness of your A8!
No more heavy shaking!
Before you print make sure your printer is well calibrated. It is possible to print left and right at the same time but I would suggest print it single and measure it.
width: 90.7mm
Hight between the frame surfaces : 234mm

You have to disassemble the top of the printer and remove the x-axis stepper to it build in.

You can use and share the files as you want for no-commercial usage.

New to the Printing Hobby, but when i load this in Cura 2.5 the part is shown to be to big for my A8 - did i made something wrong?

I have this installed at the left top side:

just beneath the corresponding mainboard case. How do I make it fit at the top? The case is flush to the sides and I won't be able to slip the stabilizer in at the top not, at least not on the back side of the top frame part because of the top mosfet case. Any ideas?

Anet A8 Mosfet Case

These would be more effective if they just had added support for the peice right behind these. Because all these touch is the 2 top and bottom peieces. It needs a 3rd point of contact to squeez to truly give you the support needed. Not saying they dont look good. But they are not pratical to make and waste all that PLA or ABS just for looks personally. If you could just add those support grooves I would be all about this add on!

I used index cards to make it stable.

when i set them at 100% scale the total length of the part seems to be about 280mm yet the installation height is closer to 230mm..... am I doing something wrong or is all good?

Total length is 274mm and hight between the frame surfaces is 234mm.

I just installed these, took quite a while to print them however I think it was well worth it. The right side fit easily, I had problems with the left side, took a little work with a file and all fits well now. These really do make the A8 much more stable. I plan on checking the bed level, making sure all is properly adusted and then print some test cubes. I will make pictures and post an "I made one" entry tomorrow. I most likely will print the braces by Leo_N brackets tomorrow and then figure out how to install them along with the filament spool holder I am using to hold two spools of filament.

Will this also work with the A6 ?

No only A8 but the A6 I think has a closed acrylic front frame?

Thank you for your feedback.
Nice to hear.

Just fitted these without too much hassle, only had to remove the top assembly. They really do stiffen it up nicely.

Works great, a little hard to get installed though

These are a must for the Anet A8 imo especially if you print anything tall with alot of X axis activity great part!

Just fyi for anyone having issues getting these to fit. Loosen the bottom 4 screws on the upright down by the motor and pull up on the upright acrylic piece to give you a little more play to re install the top/front panel. Mine fit perfectly after this

Thank you buzzkc, yes that can help to install it.

Thanks for sharing. Will print it right now.
Looks like it could be used together with the Brackets done by Leo_N http://www.thingiverse.com/thing:1872162

Yes they are designed to fitt together I use them as well
