A few options to support the flying gantry on a Voron V2 - during building or maintenance. Sure a box or beer can works, but options are good.
MGN9 Bracket Mag - My favorite - super quick print and pop in a 6x3mm magnet. Works with any rail hole spacing.
MGN9 Bracket M3x16 - When you really don't want things to move. Remove an existing M3x8 rail screw and swap in the bracket with a M3x16. Made for 20mm center to center spaced rail holes.
140mm 2020 I-Beam - Longer print time, more plastic. Stand this up between the lower frame extrusion and the gantry rail.
