The video plays back the first test prints and fine-tuning of Macchiona.
He is building the hopper for the next car that I am planning to make me the filament.

ThingMaker is the printer that I designed a year ago and now I finally finished building.
This is the extruder designed and built by me, with my CNC milled (self-built), aluminum block.
The basic idea I took from the MakerBot MK7.
is designed in two parts which are assembled together with the motor with the 4 screws of this.
On the front you apply a 60x60 mm fan.
The pieces are designed so that part of the air arrives above the engine to cool it and the other clean air keeps the toothed pinion. This brings down the dirty air from a duct downwards.
