Ender Linear Rail MGN12H V6 Modular Carriage

thingiverse

My Ender 3 Linear Rail Mod. 7350 Blower Overkill. Compatible with the cheap V6 knockoff heatsinks. Sized for the MGN12H linear rail. Modular design although missing a 30mm part cooling adapter. I suggest using the 7350 blower all you need is the right one the left one is just for extra part cooling and isn't needed. The fan converters are just for the heatsink fan 30-50mm. The 4020 fans are my best suggestion they are very powerful. The only part in this that needs supports is the valve for the blowers. You can print the carriage without supports but you will need a bit of sand paper to sand the the slots for attaching the belts. I only added the bolts and wingnuts for mounting the 7350 blower fans to the blower mounts. Use metal screws for everything else. I can only make the knockoff V6 heatsinks and nozzles work with the bi-metal heatbreaks or the PTFE insert heatbreaks. Otherwise you will get jamming within the knockoff V6 heatbreaks. This was a giant wake up call for me to be able to use the really cheap knockoff parts and allowed me to buy enough material to play with my printer. If you have a bi-metal heatbreak that spins or is lose then replace it because it will fail. Warning! This mod comes in contact with the heatsink. The mod can deform if your cooling is insufficient or if the material is not strong enough. I am using PETG without any issues with a single 4020 fan as cooling with a max temp of 250. The standard fan is not enough for the knockoff V6 but may be good for the real one. I am not responsible for if the mod melts and your nozzle falls off. I have multiple sensors around just to make sure there is no issues and its up to you to insure your own safety with this project because the only thing holding the heatsink is plastic. I give you full access to remake this and upload it I only ask for you to keep it free. The only program I used to make this was Blender. I used the hand grip texture for the valve from user johann517. I used the compact fan converter design from user Core3D_Tech. I used the bolt and wingnut from user mike_mattala. I ran some of the files through a online stl fixer from Formware B.V. Thank you all.
