Redo of my old x-carriage. Since you can have different hotends with Precision Piezo grove mount I cut the tips of the fan ducts and made them changeable. This has the additional benefit of being able to use PLA for the X-carriage and ABS for the tips. I personally use PETG for the X-carriage and ABS for tips. There are separate tips for Mosquito hotend and for E3DV6. Note that for Mosquito you will need a grove adapter to mount it.
WRT Precision Piezo, you do not need their TOP part as it is integrated in to the X-Carriage. The only part from Precision Piezo you need is a "CLAMP". I added their STL for a clamp, one with embedded supports and one without supports. You can find original ones as thing:2841681
mounting pillar allows you to attach blowers to it, zip-tie your cables to it...
nozzle size1 is good for mosquito
nozzle size-long is too long for any hotend but you can cut off the part that goes on to the carriage and get to the ideal length of your hotend so you get above the nozzle height but still blowing in to the nozzle
I will maybe add few other nozzle designs, also a circular one that works with only 1 blower if you don't want to use two blowers..
kadica can go on top of the pillar so it can hold the flex shaft few cm above the G5 so that you don't have your flex shaft bending just after G5 as it can shorten its life
With BMG Adapter, you can use bondtech + motor direct drive with this X-carriage. It is not the most optimal setup as only the right blower can be mounted so you have single side cooling and the dedicated X-Carriage should be used really as some weight could be saved here but if you want versitility to use with same X-carriage Flex3Drive and BMG this is the way to do it. (I designed this BMG Adapter after the fact as I had some issues with G5 losing grip and striping filament so I can use the printer until the G5 issue is resolved)
