So this a derivative but i did not use any of the original parts
they did not fit into my printer ;-)
So i used makerbeams (mini 10x10x150 mm) some custom bearing holders and bearings works great!!

• Look at te stack order (see photo)
• thread to rods into the holders (snug fit)
• Place spool (2.2 kg) on spooler
• Look happy while printing (could be the fumes)
