Voron Trident GE5C Bearing Alternative - Flexure

This mod replaces the GE5C spherical bearings used in a Voron Trident with printed flexures. After having issues with excessive vertical play while using low-cost spherical bearings, I developed these as a more reliable option.

Each Z-carriage uses a Voron standard heat-set insert and an M3x16 BHCS installed from below.

Before putting these flexures into service, I ran a 2 hour test cycling each Z-motor at 50mm/sec in a heated chamber (nearly 14,000 moves).

This design is not suggested for use with the Voron TAP as the flexures introduce probing inaccuracies due to the force of the nozzle pressing on the print bed.
