Monoprice Maker Select V2 Cooling Duct

thingiverse

This duct was designed specifically for my MonoPrice Maker Select V2. It is a refined version of the stock cooler that comes with the printer, directing airflow directly at the nozzle and slightly around it. I've found it works perfectly for my needs, and I printed it in PLA just for quick prototyping purposes, but I highly recommend printing it in PETG or ABS if possible. The stock cooling fan should fit seamlessly, and I'm currently using a Noctua NF-A4x20 FLX fan (see picture) for complete silence since everything else on this printer is loud. You can also use the Noctua NF-A4x10 FLX (I actually used it for my heat break fan), which is a thinner version of mine; I simply ordered the wrong one and decided to make do with it. CAUTION: If you decide to use the Noctua fans, be aware that you'll need to use a few adapters that come with the fans. Alternatively, you can snip some wires and solder things together - I chose the route of dealing with long connectors instead. The top holes are designed for heat set inserts so you can firmly secure it in place, but I've included STEP/IGS files for anyone who wants to modify the hole sizes. The fan holes are perfectly sized for M3 screws to thread into on their own without any issues. I used a standard PLA setting for all my prints made with this material, taking my time and ensuring high quality results. You won't need any support for this print either. If anyone needs specific dimensions or access to the 3D files I used to model the fan duct around, just let me know and I'll be happy to share them. Feel free to ask any questions or suggest improvements - I'm here to help.
