APC BR1500G Back-UPS Pro Anti-Tip Feet

These battery backup anti-tip stabilizers fit around an APC BR1500G Back-UPS Pro unit or the matching battery expansion to prevent it from tipping to the side. The sturdy triangular shape increases the footprint of the unit to improve stability, and also enforces spacing between the Back-UPS Pro and its battery expansion for better airflow.

Each unit needs two stabilizers, one for the front and one for the back. I can't guarantee that these will never let your UPS tip over, but it'll drastically reduce the risk.

3D printing recommendations:

• Print in ABS or PETG, or another plastic with good strength and heat resistance that won't get brittle over time.
• You'll need to position it diagonally on a Prusa Mk2/3/4 bed, or other similar sized bed.
• Use a brim to prevent curling and warping. If you have a Prusa you may need to reduce brim width to get it to fit on the print bed.
• Supports aren't necessary.
• Use an infill of around 50%.
• Use a glue stick as needed for adhesion and release, especially on smooth PEI build pates.

Using the anti-tip stabilizers:

• Position them so that they don't cover the ventilation grille on the sides.
• I recommend using an anti-slip mat or rug gripper mat under the stabilizers to prevent them from sliding.
• For even more stabilization, skip the anti-slip mat or rug gripper mat, and use Command Strips to firmly stick either leg of the stabilizer down to the surface beneath it. This will also help prevent the stabilizer from bending at the inside corners.
