As requested by the user Printer Let, here is my version of the Y tensioner for the Ender 3 Pro with 40x40 V-sot Profile.
I don't have an Ender 3 Pro, so I suppose the hardware is the same of the Ender 3 base...the model has been prepared by modifing the existing Ender 3 Mod - Y Axis Tensioner, so if somebody have the possibility to print and try it, any feedback will be really apreciated!
Update of 21/12/2018
Modified the body according the Feedbacks received from users Arti4eveR and Ratheon (Thanks guys for the precious feedbacks...! )
Modified the body for fit correctly with the fixing screws on the lower part of the V-Slots, and lifed the position of the screw (now in line with the OEM one).
The bearings now will reach the minimum distance of 10mm from the face of the V-Slot profile to make easy the installation; increased the clearance for the bearings.
Increased the clearance between the body and the screw (as suggested by Josparky)
As already stated, I cannot check by myself the fit on the machine because I don't have one, so I am working only with your comments guys.... so, as usual, any feedback is more than welcome!
