BIQU Hot Bed MOSFET Power Module BOX

thingiverse

This is an enclosure designed with a lid and openings for air cooling, allowing you to conveniently operate the MOS module by simply opening the lid. This enclosure is specifically designed for v1.3 modules, which feature a lower MOSFET heatsink that was unnecessarily oversized in previous versions. If you're using a previous version, you can try breaking some air vent gaps from the lid to make it work, but otherwise, the lid won't close properly. Several lids are provided, so choose your favorite one. Fixing screws and hexa nuts come with the enclosure - four M3x10 ones in total. You'll need to drill holes for fixing it to the chassis as needed, as no support is required. ABS printing is recommended at 30% infill. Once printed, clean up or sand the hinge attachments and press fit the lid onto the box by inserting one of the lid pins first, then the other. The two teeth on the closing mechanism are smaller, so sand them down a bit until you feel the lid closes and opens smoothly (not too tight). The base doesn't provide mounting holes, so drill your own as needed. These modules are highly recommended due to their exceptional performance. They contain NPQ030N06 power MOSFETs capable of handling 200+ amps with extremely low voltage drop, along with an optocoupler that works cool even at 25Amp loads. You can easily find them for under $5, making it a nice upgrade if you have a powerful DC hotbed. My own setup works great at 24v/18A, and I was tired of using relays and low-quality SSRs until I discovered this module. Now all my machines are equipped with one of these, and I'm thoroughly enjoying the results. I've included a picture of a used module for reference purposes. Enjoy! UPDATE (29-NOV-2017): Lid vent holes were misaligned by 1mm in the original design. This didn't affect the lid's functionality, but I've updated the lid model and FreeCAD sources to reflect this change. Three additional lid models have been added for your convenience. If you want to see LED lights, I recommend printing the lid in clear ABS. The diameter of M3 hex nut holes has also been increased. You can check out pictures of one of my builds to get an idea of how it looks. A groove has been added to the lids to make it easier to open the box using your nail.
