Gridfinity Magnet Holder 5mm Remix

I loved the original bin for my 6mm magnets, because it stores them in a low-profile position that fits in a drawer! Shocking, I know. Some of us like clean desks (though my current desk would imply otherwise…).

However, I only have two sizes of smaller magnets handy right now: 6mm and 5mm diameter. Woe is me! The original model only support 6mm and 4mm! Whatever shall I - I just took the 4mm and cut the holes (and back-side interlock thing) a bit wider for 5mm. Works great.

Because this is just the 4mm diameter magnet holder rack thing but cut with slightly larger holes, the only new piece you need is the one in this remix. You can use the 4mm base in the original files which fits a set of 4 of these perfectly, along with either the 1x1x3 gridfinity bin in the original or just a normal 1x1x3 bin (with no scoop and no tab) you find or generate somewhere.

Print Settings

Pretty much anything reasonable should work, but this is what I used (for both this remix and the original files):

• All okay with PLA. Matte in my case for some reason. Using it up I guess.
• Infill: 15% Cubic
• 0.24mm layer height (The “Draft” mode for the X1C in Bambu Studio, if you use that)

Tips and Tricks

Because these are relatively strong magnets, they tend to either attract or repel each other as you put them in. And if you don't get the polarities just right, you won't be able to get two “racks” as I call them to sit next to each other like in the second photo. Here's how I do that:

• Slide your first set into one of the edge shafts. For 5x2mm magnets, I can store 11 per shaft with an extra on top to make 12. Just stick with the 11 for now.
• Now, flip your stack of magnets so that the shaft immediately next to the one you've already filled is being installed with the opposite polarity. This will be a little difficult and you'll need to hold tightly, but it isn't too challenging.
• Continue this pattern until you get to the end of the “rack.” The top of the rack should have magnets exposed with opposing polarities, i.e. N - S - N - S - N or S - N - S - N - S.
• Start the second rack, continuing the alternating pattern. This means that the first shaft you fill on the second rack should have the opposite polarity of the first shaft you filled on the first rack.
• Continue this pattern, alternating each shaft, until all of the racks are filled. Because the polarity of each adjacent column is flipped both vertically and horizontally, the racks will want to fit together nicely in pairs.

You can theoretically also do this by flipping with every rack, but you cannot keep all of the magnets facing the same direction. Doing so will cause the racks to want to repel each other.

If orientation is important to you, I'd recommend either printing one of the many excellent magnet dispensers out there, labeling your racks, or just making sure you have a labeled magnet or a jig set up for whatever you're using these for.
