## Update

• Added a profile containing a standard bin (1x1x3u), thank you for your support 😊

  [https://makerworld.com/models/627610-optimized-gridfinity-magnet-holder#profileId-880198](https://makerworld.com/models/627610-optimized-gridfinity-magnet-holder#profileId-880198)

Optimized the dimensions of each component based on Gabriel Poleze's design.

Magnet holder (cartridge) and bin fit more tightly now. The back of the cartridge is designed with size text for easy identification. 

Two sizes of cartridges have been designed (Based on what I have) for 5mm and 6mm in diameter.

Each cartridge has four slots, with the magnetic poles of adjacent slots recommended to be placed in opposite directions, as shown in the figure below:

Each slot can hold a maximum of 14 2mm-thick magnets.

One bin can accommodate 4 cartridges, available in 3 types:

• Frame (without a bottom)
• Box (with a bottom)
• 1x1x3u standard Bin

The default profile is a combination of 4 × 6mm cartridges and box.
