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?
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):
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:
Z endstop (http://www.thingiverse.com/thing:82519):
Adjustable Z endstop pusher:
Wade extruder with hot end:
Extruder wires guide:
Extruder back side:
Extruder top side:
Hot end is mounted using aluminium groove mount plate:
Extruder idler side. Springs are taken from cheap office puncher tool:
