Cobra Carriage - E3D V6 Carriage - Anet A8 / Ender 3 / CR-10 / Mini V Slot

thingiverse

*** UPDATE 05/09/18: I have added a carriage version for rods with 46.5mm centre to centre distance, which will fit the newer A8 with four bolts in the stepper motor on X axis. Also added shroud V3 with integrated fan duct. You shouldn't need any bolts for the 4010 blower with this shroud as the fan clips in quite nicely *** *** UPDATE 20/08/18: I have included a carriage plate for the Ender 3. This will also work on CR10 and its clones too, I presume. It is divided into two parts so can be printed better. WARNING: You need a slightly longer belt than stock to use this! *** *** UPDATE 09/08/18: I have added a new fan shroud design which will fit perfectly around the 4010 blower fan and also allows for easier access to it when cleaning or replacing it. This is compatible with both M3 and M2 screws. Please update your files accordingly. I suggest supports only touching the buildplate, with no roof, and print the body as it comes in the STL. Block supports from being created in the nut trap and bolt hole else they will be a pain to get out. If you want to use a 40mm fan (ie Noctua), you can use this adaptor Print in ABS or PETG. PLA is likely to soften and warp for the fan shroud. Required Hardware: 1 x M3x30mm Bolt to go through the back of the fan shroud and clamp it to the E3D cold end. 4 x M3x15mm Screw to attach 30mm fan 2 x M3x20mm Bolt to go through E3D clamp into main body - 2 x M3x10mm Bolt for mounting Bltouch 5 x M3 Nut. 2 for E3D clamp, 2 for Bltouch mount and 1 for Fan Shroud clamp 4 x M2x5mm Screw to attach 4010 blower and its duct. Screw duct from inside edge, closest to the hot end 3 x igus RJ4JP-01-08 polymer bearings or LM8UU linear bearings 1 x E3D V6 or V6 clone 1 x 30mm 12v Fan OR 40mm fan using this 1 x 4010 12v Blower Fan 1 x Bltouch or 3Dtouch sensor Assembly is pretty straightforward. Bolt the fans and sensor to the shroud before installing on the E3D. You may need to use a flat screwdriver or something like that to pry the slits on the bearing carriers as they are tight to get in. Belt holder has been designed around a "GT2" belt from ebay.
