Top Adjustable Voron Beefy Z Idlers

I switched to BFI and BZI from Clee on my Voron V2.4 and like them a lot. I only had one issue, everything related to adjusting the Z Idlers. Getting to and adjusting the the downward facing BHCS were a hassle, especially the screw closest to the frame. This becomes impossible when adjusting them to set the belt tracking with Z in motion. It was also a pain to either reach in from the front for all four or taking off multiple panels to get to them a little easier. Lastly the adjustment screw length had to be exact or you risk hitting your top panel.

To resolve all of these I flipped the screw to be accessible from the top. I also changed them to SHCS so they may sit flush within the body of the idler.

Now I can access all four idler adjustments all from removing the top panel. I can adjust them safely while my Z is in motion to ensure the tracking is correct as well without risking getting pinched. Lastly you can use any length screw you need with only needing to watch for clearance on the gantry when nearing your maximum Z height.
