Anet A8 Filament changing upgrade
At first, changing the filament was always a nightmare with this printer. The so called "cold pull"... Not too quick, not too slow... Well, it jammed more than it worked. So... I've done the following upgrade, making it easy to access the extruding block. It's basically a hinge with a magnetic lock. The contact between the heat sink and the extruder block is still guaranteed and the heat dissipation is practically as it was before the upgrade.
