Mini Plastic Roll Holder

thingiverse

I noticed that most spools and holders are WAY too big to print. At least for my Printrbot Jr, so... To do some people a favor, I made a smaller scale version. Features: 2 3mm holes for screws, nails, or thumb-tacks for wall suspension 3 1/3" rod for bigger hold area Instructions Printrbot Jr Users: Set all speed settings to 20 mm/s, but solid infill to 32 mm/s. The bottom layer ratio to 1. Set nozzle diameter to 0.6. Infill density to 0.1 - 0.3. Travel to 68 mm/s. This should work. It has to go slow, unless you have a really good fan to cool it off fast enough to prevent bending and morphing.
