CR10S Chimera Mount with dual 5015 part cooling fans
with optional Hotend 5015 cooling fan w/ BLTouch mount

Update 2019/01/20 - I have changed the design of this object to a modular design that allows you to adjust the height of the fans for those that may have different setups, the base also include a bracket for attaching a cable chain or using a zip tie to attach wiring.

The original files are still available in the download if you prefer that version and are listed as "old".

E3D Chimera mounting bracket with dual 5015 radial part cooling fans integrated into the mounting bracket. Due to poor cooling performance from the stock 30mm fan for the hot end heatsink an optional 5015 radial fan bracket w/ BLTouch mount is also included if wanted. A noticeable improvement in cooling of the chimera heat sink was seen with using a 5015 fan in my experiences.

To make use of this setup will require significant changes to your printer. The stock control board does not support the dual extruder setup, in my case it was replaced with a Rumba controller board, however any controller capable of dual (or more) extruders should be capable. You will also need an additional extruder (stepper, extruder hardware) and mounting bracket, It is possible to get the full 300 x 300 build volume access using both extruders with the stock CR10S frame. You will need to create a new X min end stop bracket (not included in this release) to extend the print area, and also change build area firmware settings (X travel 320 minimum). It is recommended that you have a good comprehension of your 3D printer, Marlin (or other firmware), etc before stepping into these changes.

All parts are printed in PETG, using 0.20 layer heights @ 40mm/s with no supports needed. I have not noticed any major issues using PETG this close to the hot end, though the part cooling fans may discolor or slightly deform nearly the heater blocks if fans are left off for long periods of time while hot ends are active.
