Improvement Request - Cable Header Block

Picture this:

You have a perfectly dialed in machine and a sensor dies.  You pull out a replacement from your on hand stock to replace it (to avoid the shipping delays you wisely keep extras of everything that could fail).  But then you realize, you have to disassemble the Prusa to replace the sensor!  There goes your perfectly dialed in machine.

 

But think instead if there was a cable header block.  The cables all run form the board to a point on the extruder.  From there, all the sensors on the extruder plug into that block.  When a sensor dies, you unplug it form the block, remove the bad sensor, replace it, and plug it back in.  No disassembly needed, no removing the cable sleeve and putting it back on, and no recalibrating needed.  Quick, easy, painless.

A test of the first layer calibration is needed, of course, just for paranoia's sake if nothing else, but even if calibration is needed again, the replacement was so very much nicer and easier.

Can this be done?

RE: Improvement Request - Cable Header Block

If you want to do it yourself then yes.  The mk3 is a highly modifiable machine.  I don't have a block as such but my extruders heater cartridge, thermistor, parts fan and extruder stepper all have in line connectors. 
I can replace my thermistor is minutes and I don't have to do anything except run a PID tune.  Although even that could wait if I needed to resume a print.   About the only things I have to worry about are the Pinda or the extruder fan which are both still as originally designed.

Basically I rebuilt my Mk3 with a geared extruder so I decided to make a few other additions while I was doing it.
