i3 Adjustable Y Belt Holder for GT2 & T2.5

I decided to combine the designs of the Prusa i3 Adjustable Y-belt Tensioner & Holder and i3 Rework X-Carriage for GT2 & T2.5 together into a new Adjustable Y Belt Holder. You can attaching T2.5 or GT2 belts much easier and without using zip ties and of course, adjustable.

Ah don't mind the funky colors, I'm testing the new E3D Cyclops and had some Navy Blue (60%) mixing with a white (40%) to get a little blue. As you can see, not all filaments mix well. :)

BOM: 1 M3x30mm bolt & nut and 2 M3x15mm or 2 M3x10mm to attach to build plate.

Is this intended to work with the mk2 as well? Just installed it on mine and believe it's colliding with the front and back endstops.

Me encanta el diseño

lo descargare para probarlo

un saludo

is this compatible with the anet a8

I've looked the Anet a8 design and I don't think so. The holes aren't the same spacing.

Could you provide the CAD?

Sorry, don't have any. I used 123D Design. It's free



Glad you like it. :)

Wonder if this will work for the Wanhao i3???Anyone? If not Id love to see this for it!

Hmmm, not such. I've seen pictures of the Wanhao i3 but it looks like a lot of the design is steel.

Simplicity and excellent design. It is so much better to conect one end of the belt to the carriage, the other end to the removable part, then just plug in and tighten a screw. Thank you.

Just installed one in my i3, really nice upgrade from the silly y-idler with a screw through it from the i3 rework, didn't like that setup, split on me the first time I adjusted it and had to put zipties around it to keep it from breaking (I printed a version sans adjustment, just a round hole), only real suggestion for an improvement I could make is perhaps swapping the M3 screw to a M4 screw (easy for me to change myself and I have for my spares bin), a bit hard to find long enough M3s to get much adjustment range, with the longest I found easily in stores nearby I get about 5mm~ of tensioning range.

Really like that belt holder setup, much nicer than the silly toothed plastic and zipties version.

Hi! I really like your way of attaching the belt (been using your X carriage for a while now with great success). Any chance of uploading a non-adjustable version for those of us still using the tensioner in the front? I believe that would make the part even simpler and more solid. Thanks anyway.

Yeah sure, give me a day or so and I'll have it up for you.

Thanks, looking forward to it!

Great design, I've been looking for a better adjustment for the Y belt and this is the best I've seen so far. What did you do to replace the old Y-Idler? Just a quick part to hold a bearing? Do you have that file as well?

I used the original Prusa i3 Y-idler from GitHub. The one that came with the i3 Rework had a bolt sticking out of it that was kind of ugly. So customize my printer a bit, most of it is the i3 Rework. You can go here if you want to use the original y-idler. It's a SCAD format though.
