Tronxy X5SA Pro 330 Z-axis support (Slide in place).

thingiverse

If you look along the Z-axis supports (the ones with the bearings), you'll probably notice that they curve due to the weight of the bed. This was a concern for me as I don't want the bed flexing as more plastic gets added to a print. Many of the Z-support designs avavilable require that you dismantle the entire Z-axis to insert them. I designed these to just slide into place. You need 4x m5x30 nuts and bolts, and 4 m4x10 bolts. original link and maker here : https://www.prusaprinters.org/prints/56446-x5sa-pro-330-z-axis-support-slide-in-place included also, a 24mm version suited for antibacklash nuts
