similar to the LTT cable management system but uses different magnets that can be found on amazon along with adhesive backed metal strips. i printed the first layer at 110 % and press fit the magnets. each size uses different sized magnets. i applied the metal strips to the bottom of the desk near the back in a 2 x 2 pattern for optimal coverage. I will be adding more models of this type to my page in the near future.
small can hold around 3 to 4 small cables such as USB-C
medium can hold around 2 to 4 large cables such as HDMI or 10 to 12 USB-C
large can hold around 4 to 6 large cables such as HDMI or 15 to 18 USB-C
