I collect bottle openers, one for each vacation destination or brewery visit. They’re kept in chronological order on a rack I made in 2017 from the oak cabinetry panel of our old kitchen refrigerator. To be honest, it was 80% full the day I finished it nine years ago. Keeping them under the 3D printers and over the PCs in this high traffic area is problematic, they are frequently knocked down. I needed a new sensible extensible solution. It makes more sense that they’d be kept on the “beer fridge” so I designed a modular magnetic rack system for them in FreeCAD . The rack is a 290mm x 25mm dovetail that just barely fits on the Prusa2 (Klipper/RAMPS modified Prusa i3 MK2s) print bed. My original design was 300mm long but didn’t fit on the bed, so I shortened it in the spirit of “design for manufacture”. I printed the hooks below on Sam Bell 2 (a home built i3 clone functionally identical to the Prusa2). I chose blue and white to match the colors of the München Biergarten magnet already on the white refrigerator. After some iteration to determine adequate spacing, tolerance for mounting the 4mm x 2mm magnets, and a few more iterations to get a good fit for the hooks on the dovetail, I started cranking them out in PLA. The hooks print best one at a time so I spaced them out and for the first time I configured and used sequential printing. Sequential printing can print multiple parts but it prints each one after the other instead of all at once. They all turned out great. Side note: My fathers father, William “Herbert” Williamson fixed clocks, watches, and jewelry. He had many unique and interesting tools. When I was four years old I always wanted to play with his brass and rawhide hammers. I remember occasionally seeing them when he opened the lower left drawer of his workbench and I think I only got to touch them once. I can hardly imagine the stress level while handing a four year old a hammer in a small clock workshop. I’ve since inherited them and it gave me great joy to finally be able to use the rawhide hammer to drive in all the magnets. It’s all done and it turned out better than I expected. Note: The silver bar on the freezer door contains nine promotional bottle openers from one visit to the 2023 Design-2-Part manufacturing trade show, whereas on the refrigerator door the bottle openers are each unique to a trip in chronological order. Bonus Content If you are curious, this is what the inside looks like. I occasionally like to take a picture after restocking which is roughly annually I realized after digging up these photos. This is probably my biggest fitness headwind but it brings me joy. I’ve veered waaaay off the topics of design, making, and 3D printing. Now back to your regularly scheduled programming.
