About this 3D model
You want to connect a filament spool to your Prusa Mendel? The filament spool will balance on two treaded rods. This mount is a bit shaky, but so far durable. Too much load might cause damage. So use it at your own risk. Update: The lower structure is not stable enough. At 37°C room temperature and a weight of 2 kg the arms bended. The spool mount broke. Please upgrade to the new fortified spool mount. http://www.thingiverse.com/thing:29142 Or use far less weight.
