This is a derivative work of Wade's Geared Nema 17 Extruder by Wade.
Also this is a revised version of TB-Clamping - Wade's Geared Nema 17 Extruder http://www.thingiverse.com/thing:5401
As before TB-Clamping - Wade's Geared Nema 17 Extruder, I found that the printed clamping is very easy been cracked. So, i'm re-design again and this time i'm did a separation of extruder body and thermal barrier clamping. Also i'm added a 2nos M3 holes to fix the 2nos M3x45mm(L) screws to hold a force from extruder.
