Super simple dual filament spool holder for Rostock Max

myminifactory

I Made these little gadgets up to hold dual filaments on the Rostock Max stock mount. They worked great for ages until I got a Polybox. I then found other filament spool feeders/holders online, but they were mostly over-the-top things that took ages to print and tons of plastic. These will not! Just use a 12mm tube (a carbon fiber tube is pictured) between the two stock towers on the Rostock Max. I put some tape on the end to ensure the filament spools didn't slide off. You could also print a 12mm tube, but it's best to use something slippery and premade like the carbon fiber or plumbing pipe.
