GolemC heart

golem's Heart (golemC)

new extruder, thought out from scratch to be compact, simple, accesible and light. for the golemC "stone" printer

still fine tuning design, stl's soon, openSCAD files will follow.

it's designed around my very first aproach to drive roller, refinded by trial and error. instructions how to mill one will follow, feel free to make one for yourself but please, if you want to buy one, make sure the autor gets some material credit and buy here (http://mojreprap.pl/index.php?route=product/category&path=24) or contact me.

small crescend shaped teeth grap firmly (5 kilo for the smooth compact one from the vid) while cutting in with ease. se here for easy cut in: and here for gravity feed:

6mm shaft and small 6x13x5 ball bearings reduce weight to about 90g without engine (the red body/black gear ones)

it's milled to fit 3mm filament, but works fine with 1.75 too. still i will try to make even smaller design for 1.75mm specific.

2 base flavours: - compact - more mendel friendly - big gear ratio for open top printers and heavy filament pumping
