Printrbot Simple Metal Z-Axis Upgrade Threaded Rod Stabilizer

thingiverse

The new Z-Axis upgrade is a game-changer, bringing exciting improvements to the simple metal design. However, there's one catch I've encountered: when homing the printer or executing large Z-moves, the wobble on the top of the threaded rod becomes a concern. To address this issue, a stabilizer can be attached that glides over the threaded rod beneath the handle (if installed), preventing vibration during big moves. Initial testing has not been comprehensive, as I haven't taken advantage of the expanded Z-axis range for a full print job yet. Nonetheless, moving the head to the top of the axis and taking some rough measurements suggests that the increased dimension won't drastically impact the usable Z-space. This stabilizer tends to stay in place without needing additional support, though it does come with holes on either side where 3mm screws can be inserted for added security. As a bonus, this component can be printed with its base facing down, eliminating the need for any supports.
