My cheap 400w Chinese power supply in my HEVO went bad. Not wanting to wait to get a new PSU from overseas I went with what I could get in my area and wanted to go with a better quality PSU. So, I decided on two Mean Well LRS-350-24 power supplies double stacked. I remixed constantin33's great power supply mount for a single, standard size power supply so I could double stack the two Mean Wells. You can use this mount with one or two LRS-350-12 or LRS-350-24 in any combination (for example you might want to use a 24v supply for your hotbed and a 12v supply for your printer or vice versa). I am using one 24v supply to power a Duet 2 Maestro and led strip and the other 24v PSU is powering a heatbed through an external mosfet.

You can use another layer height such as 0.2mm or 0.24mm for a faster print. I found 25% infill to be adequate but you might want to use more to make the mounts stronger.
