Wanhao i3 fan shroud and pi zero enclosure

thingiverse

UPDATE: I cannot recommend using this setup. I've been having a lot of problems with the zero4u usb hub, which disconnects randomly and stops a print part way through. This is a known problem, but I thought it was resolved. As a result, DO NOT USE THE HUB! I'm going to come up with a better solution, but I haven't figured it out yet. This fan shroud attaches to the back of the power supply on the wanhao i3 or monoprice maker select v2. It allows you to upgrade to a 100mm exhaust fan, as well as mount a raspberry pi zero w and a zero4u usb hub inside the enclosure. https://www.adafruit.com/product/3400 https://www.adafruit.com/product/3298 I made the holes so the hardware could screw directly into them, no tapping or nuts required. For the fan: M4 screws For the raspberry pi zero and pi4u: 4-40 screws For the power plug/switch: M3 screws (same size as what it originally used, but the holes are deeper to allow you to use longer screws) For the mounting holes onto the back of the enclosure: M3 screws (same size as what it originally used, but longer screws should be used)
