I modified the official Panda Breath mount STL (available here) for the Snapmaker U1 to add "feet" and magnet holes to mount the Panda Breath horizontally on the left wall of the Centauri Carbon, routing the power cable through the riser.

3 files are included:

• Bottom mount (requires 2x 8x2mm magnets)
• Top mount (requires 1x 8x2mm magnet)
• Spacer to screw into the mounting hole (requires 4.5x3mm M3 heat insert and short M3 screw + 1x 8x2mm magnet)

Rationale for mounting it on its side:

• left wall doesn't fit upright because of the inside spool mounting point
• right wall upright mount would mean power cable is routed from the door side around to the back
