I had a problem with my power strips - their magnets weren't powerful enough, and was slipping.
This mod replaces those 20x30x3mm ferrite magnets to 4x (not-so-cheap) Chinese 10x10x3mm neodymium magnets.

Things to prepare

  1. Buy the number of magnets required. I used 10x10x3mm magnets, but 10x20x3mm ones should work too. 4 magnets per 1 ferrite magnet is needed, or 2 if you're using 10x20x3mm ones.
  2. Get some epoxy glue, or glue that sticks well on metal and doesn't have problems with mechanical shock. I.e. NO CA GLUE! (although it should work, I cannot guarantee its long-term reliability)
  3. Get some thin anti-slip sheets. I used these ones, but any sheet should work.
  4. Use a slicer with polyhole generation. I like to use superslicer myself.

Installation

  1. Use a screwdriver to remove the original magnets.
  2. Sandwich the printed bracket with the original metal one, and the magnets.
    The magnets should be placed in opposite directions. (If one has S facing up, the one next to it should be N up)
  3. Once checked it can be aligned, disassemble and put glue between the parts.
    You might want to have some cooking sheet underneath to protect your desk from spilling glue.
  4. Cut the anti-slip mat in the desired shape (10x30mm), and use glue to stick on the magnets.
    Note that it should cover the highest point in your setup - usually the surrounding metal part.
