Not satisfied how the “squared” mod tensioners looks like, i decided to remix the fessyfoo version for make my own version of X axis tensioner.
I think it looks quite OEM, is easy to print and require only one idle GT2 pulley (I used a 20 teeth version because I found it already at home... ) and a M5 screw ( used one of the OEM screws recovered after the dual Z upgrade.
Hope you like this version.
Update of 09/09/2018
Major Update [ Mk6 ] of the body ( for give more torsion strenght and make it also easier to print ), and the screw ( that now can be printed laid on the bed insted of in vertical; this give more strenght for the belt tensioning and avoid breaks in the screw area ).
Also I removed the Cr-10 logo from the knob, because the piece itself looks more "clean".
I've made several test prints, and to me, everything fit correctly without post-processing, so please take it as it is!
Update of 18/09/2018
Due to the fact I've already prepared the pieces for another project, I added the X Tensioner files for solution that uses GT2 pulley and the OEM bearings.
The body and the screw are different for each version, so cannot be swapped (different overall dimensions of the wheels, The knob is the same, but I added 2 files for make easier life to whom will download! Furthermore, the adapter is foreseen with the nominal diameters, and must be scaled in order to fit correctly the tolerances on your bearings.
The GT2 version requires a Button Head M5x20 screw, and the F688Z version requre a Button Head M4x20 screw.
Please note that the GT2 version is preferable, due to the fact that has the same diameter of the pulley on the motor, and make the belt remain "straight" during the movements.
Update of 21/09/2018
I've been asked the version for the OEM bearing + OEM M8 Screw.
Please note that I don't suggest to use this version because it make the body of the Screw too weak in the holes area!, so, use it at your own risk!
Update of 08/03/2019
I've been asked a screw GT2 version, but with the seat for a M3 scew and M4 screw, so, added the STL for these two versions.
All the new files are the last Version
The tensioner has been designed for the CR-10 (and relative versions), but can be used also for the Ender 3, and similars printers that uses 2020 V-slots profiles.
