Summary

Y belt attachment for Anet A8-B printer. This is a remix of Simhopp's belt_y_3.skp from thing:1433295 for Anet A8-B printer (the one with aluminium 3-part heated bed stand and 12 x 20 mm screw hole distance).

Choose the STL that better suits your printer's heated bed stand configuration, see the pictures.

For 4mm base part You will need two M4x15mm screws (saved from original attachment) and two M4x6mm flat head screws.

For 10mm base part You will need two M4x20mm round head screws and two M4x6mm flat head screws.

Update 2016-12-12: Added "high-base" part.
Update 2017-01-18: Increased base height by 1 mm to eliminate a subtle belt bending.

I had this in use, but after i changed the belt to a higher quality version it no longer worked as the belt slipped through.

Same problem for me... Any idea?!?

Comments deleted.

I used the 4mm version. Printed with 35% fill. I have a brace for the rear stepper motor (https://www.thingiverse.com/thing:2225276). I had to snip the corner off of the Y-belt attachment part (this part) so I could releave the slight interference. This initially cause my Y-axis limit stop to not work. Other than that, so far, great model/part thanks for creating and sharing it.

Anet A8 frame reae brace y-axis

Took my printer apart. Went to install. Belt slips out. Will wedge 3x5 card in there, so i can put my printer back together. Think we need a better design.

Great Design, my belt sits a bit lose in the shorter part but with one layer of blue tape on the smooth side of the belt, everything fits nice and snug.

Is this part valid for the Anet A6?
I think I need the 10mm piece

I don't own an A6, but judging from photos I think the belt holder needs more space between the bed frame and the belt. I can make holder for A6, If You measure the distance between the belt and the bed frame bottom. Or You can make it yourself just using SketchUp extrude tool, source is available.

I'm going to print the 10mm and I'll comment if it's worth it or not.

What size screws are needed for this project? (Size & Length)

For "low-base" part You will need two M4x15mm screws (saved from original attachment) and two M4x6mm flat head screws.

For "high-base" part You will need two M4x20mm round head screws and two M4x6mm flat head screws.

It's stated in the post-printing section.

I printed this with 4 layers (bottom, top, sides) and the "long part" is good enough but the short part, the belt travels almost freely, so it won't work.

Is there any recommended setting to print this?

I have the same issue - the belt slips out of the short part when I tension it a bit

Can You please measure your belt thickness?

Here is the version for the thinner belt: http://www.thingiverse.com/thing:1875878

Y Belt Holder for thinner replacement belts (Anet A8)
by Nnivo

I have the Gates Power Grip GT LL-2GT belt (fibreglass reinforced) and the original one is too loose and the thin one is to tight. I would need the exact average between the two. :)

I'm getting around 1.6mm, I'll try that one soon, thanks! (Maybe my printer is miscalibrated, too)

Hi! What did You mean by "travels almost freely"? Did the belt skip the holder teeth when tensioned? Did You use a stock (1.7-1.8mm thick) GT2 belt? A close-up photos may greatly simplify the diagnosis.

This thing should print OK with the usual settings You use to print other parts, e.g. 0.2 mm layer height (for 0.4 nozzle), 3 vertical and horizontal shells, 20-40% infill, 220-240 °C for ABS, 190-210 °C for PLA. If the printed part doesn't fit, then, probably, something goes wrong - You need to carefully examine printer construction, belt tension, printer calibration, slicer settings, etc.

I made this and it works amazingly!

Works great on my Alunar Prusa i3.

Awesome...brilliant!!!!

I used the belt_y_3 one from here http://www.thingiverse.com/thing:1433295 and the 2nd set of screw holes were too far to fit, it still worked with 2 screws, but much better if 4 can be used!

Thanks for this!!!
