I recently picked up a UPS to add to my server rack, which when installed, drooped at the back more than I would have liked due to the weight and the only support being at the front. I searched for a print to support the back so that it would sit level and came across this one by MK (https://makerworld.com/en/models/1400438-19inch-1u-support-brackets-for-equipment#profileId-1452233).

I have remixed the original design by:

• Adding an extra wedge to increase both lateral and vertical strength.
• Scaled up the size on the z axis from 3cm to 10cm to suit my rack depth and also provide extra thickness on the base (10mm bolts recommended).
• Rotated to print at 45 degrees so that the layers lines between the base and support section are not a weak point.
