Like already mentioned I'm using the Toolhead from the E3D-Toolchanger and I'm quite happy with this decision. The overall mechanism works like a charm and the stall detection of the coupler works flawlessly until now. 

Altough the E3D-Guys are quite skilled mechanically I think the design of the cover and the cable management could've been done a little bit more thoughtful and with a proper design statement. So here we are with a neat cable solution and a custom Toolhead-Cover with underlines the industrial look of such a coupling-system (always my opinion).

The toolhead-cabling

For the Toolhead I've designed a small 8pin-Connector and cable housing so you can just plug/unplug the coupler and the Z-endstop-switch. 2pins are not defined yet but already implemente. Maybe a toolhead light or additinal 2pin sensor...

The toolhead cables are directly soldered to a XH2.54 Terminal and then glued in place. 

The Toolhead-Design (Cover):

For the Toolhead I've designed a new cover. Above the comparison between the E3D-Cover vs. the new one

Personally I've found it quite pleasing to see the gears of the coupling mechanism. Additionally you're able to see if the coupler is locked or unlocked. The toolhead-cover mounted looks quite nice and gives a proper statement.
