Going to borrow my girlfriend’s Dremel to grind the welds off my salvaged 18650 cell ends when I visit, but realized a way to hold and feed it vertically would made things much easier. Not about to haul my drill press there and it's far slower than the Dremel, so instead I remixed a mount for her model tool I found online into an arbor press attachment. Was a little worried about the thin connecting web even after I beefed it up a bit, but it seems quite solid. Fair number of people have used it, so I’m fairly sure it’ll fit the Dremel. Won’t have my printer to print a new version, but I can always file or shim.
Come to think of it, I should design a depth stop. Should’ve thought to add it in the main print, but I can bolt it on or glue it easily enough. Could really make the grinding process less error prone.
