   ==== What makes that DESIGN UNIQUE from original cooling?  ====

                    ---      Much better cooling, thanks to powerful WS7040 Fan      ---
 

Its a controlable fan, like regular one

Layer cooling time is not a problem right now, thanks of that cooling, you can print PLA much faster, with nice looking prints
 

Just look at that power!!! 

                                                                     Features: 

- Low Weight (ONLY 21g)

- New cooling drops min. layer time and speed up the overhangs 
(faster prints)

- New compact design (more printable area than previous version)

- Supportless top part of design

- Easy assembly

- also supports hotend from Creality K2 Plus
(look for file cpap_for_k1_with_k2plus_hotend_v2 (made by vdl13))
Vdl13 made remix, he adapted the model for printing in one piece and also extended it for the K2 Plus hotend
