Hot Shoe to 1/4-20 Magnetic Quick Release / LumeCube Magnetic Mount

Video:\r\nhttps://www.youtube.com/watch?v=OAIydsQTraw\r\n\r\nThese are some mounts I've designed to use as a magnetic quick-release mount for my LumeCube v2 on a Canon DSLR camera. One piece of the mount is placed on top of the DSLR, while the other piece is screwed into the bottom of the LumeCube. Each half features four magnets that securely connect when brought together.\r\n\r\nI created two versions of the mount: one for 6mm x 3mm and another for 10mm x 3mm magnets respectively. The 10mm variant is significantly stronger, which can be both an advantage and a disadvantage. The 6mm variant may come loose if the camera experiences violent shaking.\r\n\r\nThe base is secured to the camera using a screw and a wedge-shaped plastic piece. Tightening the screw applies additional pressure from the wedge onto the camera's hot shoe, ensuring a secure connection. You might not need this wedge/screw system, but it will provide added stability for the base.\r\n\r\nIn addition to 3D printed parts, you'll need the following materials:\r\n* Neewer Stainless Steel 1/4" Mounting Screw - a 1/4-20 "camera screw". A regular 1/4-20 bolt of suitable length will work just as well.\r\n* Eight magnets, either 6mm x 3mm or 10mm x 3mm. You'll need two sets of four magnets.\r\n* M2.5x30 machine screw for the 6mm variant or M2.5x34 machine screw for the 10mm variant. A longer screw is acceptable, but it will protrude beyond the base.\r\n* M2.5 heat-set threadsert - you can find these on eBay. Simply set them using a soldering iron; an m2.5 nut may also be suitable.\r\n\r\nThe parts are designed to print in the orientation shown, with the base printing vertically as depicted. The layer lines will be aligned accordingly. On the base, there's a small "pillar" that should snap or cut out cleanly, supporting the overhang above it. All these pieces can be printed without supports.\r\n\r\nThe magnet packets are slightly oversized to accommodate some tolerance, so exercise caution when setting your magnets too deep (if you do, they'll usually pull back up before the glue sets). Secure the magnets using cyanoacrylate superglue.\r\n\r\nI recommend printing the parts in PETG. For the models shown in the video, I used Priline Carbon Fiber PETG. While the carbon fiber is not essential, I do suggest PETG or Polycarbonate over PLA for added durability. Printing the base in PLA might compromise its stability.\r\n\r\nI based my design on raster's "Hot Shoe Mount" (Thing 33823), which was used as a starting point for developing the part of the base that interfaces with the camera.
