Creality K1 Toolhead cover for BCJ Linear Rail Carriage with Dragon Ace MZE hotened

This toolhead cover design was made to resolve my problems with part fan cooling after I upgraded my K1 Max to a Booty Call Jones linear gantry and upgraded my hotend to Dragon Ace with Melt Zone Extension (MZE) that effectively lowered the nozzle position by ~9mm. I didn't like original Booty Call Jones version of the cover and I found it too high above nozzle which caused reduced cooling effectiveness. This design aims to resolve these issues and in my opinion keep nice original look from Creality toolhead cover. 

I created a version with a D3vil logo which looks catchy in my opinion. If you like it as well you can pick that one instead.

This model has been designed from scratch but I used a model by Henlor as a initial guide for modeling and have taken the vent holes as is. For the logo version I used a logo from D3vil burner but fixed the asymetry in it. 

Features 

• Drop in replacement for the Creality K1 and Max
• Lowered and longer cover to match Dragon Ace MZE hotened dimensions
• Improved fan duct with circular shape
• Covers top part of BCJ carriage (original creality cover has holes for a top linear rod)
• Does not require to disconned cable from lidar sensor when removing the cover
• Interesting design with D3vil logo option
