Magnetic refrigerator spice rack set - heavy duty uses neodymium magnets

thingiverse

This is a heavy-duty spice rack that uses almost no support material (check out the photo of support material layout.) If you only have tiny plastic half jars of McCormick spices, you can easily use one magnet per jar instead of two. The vertical arms keep spices from falling out when someone slams the fridge shut or bumps into them. They are reinforced to reduce the chance of snapping off. You can read the labels without having your spices fall.\r\n\r\nYou can print single, double, triple, quadruple, or quintuple holders. The more jars it can hold, the better it stays on the metal as there are more contact points. In the photos you can see that I use a single holder for my most commonly used spices, salt, and pepper, so they can come with me and stick to the stove while I cook. I like my spices accessible but also out of the way!\r\n\r\nWhen building these, first buy magnets then print the magnet test STL file. The magnets I used are in the photos. I bought them from Home Depot for $4.50 per pack of six. The magnets should drop in snugly or lightly pop into the magnet test piece. If they don't, try scaling up or down by 0.5-1.0%. Scale the whole model to match your successful test so the magnets will fit.\r\n\r\nWhen you print the full model, be careful about cleaning out the support material from the magnet holders. If you deform the edge, the magnets will need to be forced in by popping them in with pliers.\r\n\r\nTo glue the magnets, use super glue or foaming gorilla glue. I used super glue. First, I made a shallow circle of glue inside the magnet holder. Then, I popped the magnets in, careful not to bring them close to each other and suck them back out of the holder! Then, I made another light circle of glue around the circumference of the inserted magnet so it filled the gap between the magnet and the plastic. Then, as in the photo, I used extra magnets or some washers on the opposite side of the magnet holder, so the magnets would be held in place very tightly as the glue dried.\r\n\r\nAfter the glue dried (give it at least 4 hours.) I roughed up the back of each magnet with a file and some 220 grit sandpaper. This increases friction and keeps the magnets from slipping off the shiny, slick side of my fridge.\r\n\r\nIt will not hold three popcorn seasonings jars in a row because they are a tad too large, but it will hold one or two! I also use one to hold a little bottle of PAM spray oil, which is also handy to stick to the stove when cooking.
