Final tweaks: Secure wonky hotend & Thermal insulation on the MK2a heatbed

During previous prints I noticed my hotend moved a couple of mm in the Y-axis direction (and this messes up the Z-leveling). The hotend was seated directly into the extruder and secured with a mounting plate. Now I've placed some fancy washers in the 16mm extruder hole (orange arrow below) and the E3D hotend. Now the hotend is firmly secured and not moving at all in any direction = better prints!

To make the heatbed heat up even faster I added 2 layers of PE-thermal insulation(95% heat reflection) under the heatbed.
