BB gimbals for supasorn's dual-z

thingiverse

This thing allows you to add thingirob's BB gimbals (https://www.thingiverse.com/thing:2480577) to Supasorn's Dual-Z mod (https://www.thingiverse.com/thing:2163949). I really liked the dual-z solution, but wanted a way to include gimbals or oldham couplers. The standard thingirob gimbal will attach to the original mod, but there are two problems: 1. The gimbal adds too much height, so your nozzle can't reach the bed. 2. The left-hand lead screw will skew left slightly because the top is being pulled by the belt. Usually the hard attachment to the x gantry prevents this, but the gimbal allows it. This thing modifies the lead-screw connectors for the x gantry, to include slots for two standard (.177cal) BBs (extremely cheap online, used for Airsoft). This allows the lead screw connector to replace the top piece of the gimbal, gaining enough z-height for the nozzle to safely reach the bed. Also included is a simple stabilizer for the left-hand lead screw, to prevent it from skewing outward. This uses a single 608 bearing. *Parts needed:* * 8 x plastic BBs (standard .177cal) * Tiny dab of superglue for each BB * 1 x 608 bearing (standard for skateboards) *Print list:* * 1 x left z support.stl * 1 x nut mounts.stl * 2 x gimbal1.stl * 2 x gimbal2.stl
