X Belt tensioner - remake

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2912287.

modified it to fit much better into the original right side part.

• U a little wider (+1mm each side) - for less space and so less movement
• the 4 square hole for the ball-bearing 0,5mm wider, now you can tighten the screw without blockade the ball-bearing
• M4 screws and nuts! (not the ball bearing screw, thats original)
• little knobs for centering on the metal axes! no movement

i took M4x30mm screws and they fit perfect. Will upload pictures soon

If you want the part with your name etc on it, contact me and i try my best. Thanks

Update 13.06.2018

Added part for pulleys with M5 screw.

Also good to see on the pictures how easy it is to switch filament with my Extruder Fan Holder. Switch 2 times filament white --> blue --> white during print without problems.
