About three months have passed from start of my 3D printer build. Just as I suspected, it was hard but interesting time. But what I have at now?

Prusa i3

So, it's vanilla Prusa i3 with working space 180x160x180mm, with heated bed, E3D v6 0.4mm nozzle hot end, controlled by Arduino Mega + RAMPS 1.4 with Marlin firmware (https://github.com/3cky/Marlin).


Heated bed MK2B, dual voltage (12/24V). Got damaged, but not fatally, just broken one of corners. Mounted on roller pen springs using M3 bolts and locking nuts with rosettes (http://www.thingiverse.com/thing:6599):

Heatbed leveling

Bottom side of heated bed is thermally insulated:

Heatbed cable is fixed using cable guide (http://www.thingiverse.com/thing:204666):

Some words about endstops. I'm using three-wire Makerbot Mech Endstops 1.2 with LED indicators.

X endstop, mounted using standard fork-type mount, slightly cutted to leave some space to frame:
