Needle file grip/handle

SummaryShould work OK with the cheapest needle file set you can find at Harbor Freight, AKA:https://www.harborfreight.com/12-piece-needle-file-set-468.htmlOr any file that is 3mm in diameter.Word from the wise: Take a 7/64" drill bit and drill it out a little so itll fit easier, but still tight.You could also use a 1/8" bit - SLOWLY - and use some super glue to keep your file inside the handle, but I like the 7/64" method better, personally.Print vertically, flat part of handle on the print bed.I used an Ender 3 Pro with a PEI coated magnetic spring steel bed and these turned out fantastic.Print SettingsPrinter Brand: Creality Printer: Ender 3 Pro Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 15%Filament:<a href="http://www.amazon.com/s?url=search-alias&field-keywords=Inland+PLA%2B" target="_blank" rel="nof
