Alternate Rear Rollers For HYDRA Pro

You'll need 2x M3x5 screws, 27 x 693-ZZ bearings and 2x bolts for each roller. Very easy to assemble. I made different variations that works well for me, I use one or another depending the spool used. Rollers are 12mm wide, and sadly not enough clearance on the back of the HYDRA Pro to test some other ideas I've had.
