Plan to use this - printed in ABS but will probably try again in PLA. The 11/32 nuts sold at the big orange box are just a hair fatter than the cutout. Nut width from front to back is 15/64 but the hole to place the nut is only 13/64th. Most likely can be manually shaved down but I'm just going to cut it in blender and try again.

thanks, will this fit the I3Plus?

it does not unless you remove the bottom plate.. it just needs a few more mm of clearance.. I currently have it installed on my i3Plus. I think I will print a different one next so I can put the bottom cover back on.

Any reason why this cant be done in PLA ?

Hello Marthr,

for me no, I tested and it quickly deformed even 100%, suddenly, I came back with the original screw which is really the top (well tense) or the difficulty is to screw the last screw , otherwise I'll probably go with another system if I need, but here once settled, no need to touch it.

Im using eSun PLA+ which is definitely stronger than regular PLA. mine seems to be okay not deforming. I use it on the X axis tensioner as well without no issues after 20 hours of printing.

Lol thanks for this. Not the design as i have an Anet A8 and this wont work but the way you ziptied the belt.
Helped greatly as i always had trouble with belts slipping so the fact that i rolled it like that before ziptying helped immensely.

I printed it, but the insert side of the one piece seems too large? I will post up in the made category, but the inert side gets pinched fairly well without even having a bolt in it. Not sure what the deal is? I printed it twice.

I just want to say Thank You! You did an amazing job with this, and it was a simple easy mod to achieve better prints.

I had an issue of using the nylon insert nut, aka a locknut. The nut would just spin. I had to get creative with a pair of vise-grips to hold the nut in place without damaging the tensioner. I might modify this to allow for the nut to be placed in an inset on the end that is of the same shape so that it won't spin.

But again, just a small issue, overall it was a pleasure to print and install. Thank you again!

My lock nut wouldn't fit without a hard struggle.. so I just used a soldering iron to heat it and push it in melting a little bit of the surroundings.. its definitely secured in place for good now..

Thanks for the kind words! Yes, ideally your lock nut would be placed inside the hexagonal nut opening on the part, preventing any spinning while tightening the screw. On mine, the nut fits snugly. Glad you were able to make it work.

I was at the hardware store and I couldn't remember what size the bolt was supposed to be so I quickly glanced at the project and decided that an M4 would fit, which it did. But looks like the nut is a little smaller than the 11/32" nut that you designed this for. I read the description wrong. So for anybody else...use the hardware @kevintibbets said to use :)

Will this fit the i3 plus?
