> 3 dayI have 3 Standard Ender3s and this is a much needed upgrade. The price is low enough I am not sure why anyone wouldnt pick this up. It does not come with wrenches but the kit you got with your printer has everything you need. Once I found the sizes I need I uninstalled previous tension-er and had this upgrade installed in a little under 3 minutes for each of the 3 printers. All metal design gives a good quality feel. The knob lets me decide how tight I need to belt to be.

Greater than one weekThe description says it fits the Neptune 2. This absolutely will not fit the Elegoo Neptune 2. It does not even come close to fitting the rails. If you are buying this for the Elegoo Neptune 2 don’t, it won’t fit.

> 3 dayMuch easier to tension the belt but the hole through the sheave is not bored true making the sheave wobble as it turns. Looks great but this little issue is disappointing.

> 3 dayThe toothed idlers wheels wobbled from the time it was opened. Everything else about this tensioner would be great if the idler was good.

> 3 dayGreat tensioner, well built. As someone mentioned, if your bed size is set to 235mm, the Y carriage will hit the tensioner, not a problem for me since I upgraded to linear rails.

> 3 dayReplaced a printed (PLA) tensioner on my CR-10 mini that came apart after a year or two of wear and tear. While I like printing mods in general, this is just more solid, easy to adjust and fits the rail and belt perfectly. The old printed mod was a little off and had some wiggle that led to some annoying belt rubbing from time to time.
