About this 3D model
This version is a remix from the 2019 original from Thingiverse. https://www.thingiverse.com/thing:2786671/files I made an effort to upgrade and remix it cause I Think this is easy, and far away, the best Y-Tensioner Mod for prusa.

Dont worry if you cant, its thight. Use the Pull method from the Prusa manual and screw them :) 3º - Get the “Base_for_your_pulley” (I choose the Prusa one) 4º - Put It in the Base_Holder. Later will be screwed 5º - As you can see , the Base_of_Your_pulley has two sides. One with Hex Holes, One with Round holes. 6º - Prepare your Pulley, two M3x35 and Two LockNuts 7º - Put the LockNuts in the Hex holes! Now , from the other side, Insert the M3 across the BaseHolder + Base_of_Your_pulley + Your Pulley. Screw a little , dont be rude. The Y base needs to move freely, and your pulley too!!! 8º - Now Prepare a m3x30 and another Locknut. Put it in the hex hole. Screw from behind. 9º - You will end with something like this! 10º - Time to pass the Belt across our Tensioner. 11º - Now pass the belt into the Bed-Holder Too, as shown in this image. Is easy in this step. 12º - Pass the rest of the gt2-belt across the motor and put it into the Bed Holder. You can now use 2x m3x10 bolts to screw the Bed-Holder to the Bed.. Optionally, you can put the Bed-Holder-Door to assure your GT2 BELT with 2 M3x18 and two hexnut or locknut. 13º - You will end with a tensioner like this one. Only one bolt to add or rest tension to the Y-Axis. You can do it from the FRONT of the printer, even if the LCD screen is in his place :) ENJOY!
