Prusa MK3 PSU FAN 80 mount

thingiverse

This is a custom mount for an 80x80x15mm 5V USB fan designed specifically for the original Prusa i3 MK3 PSU.\r\n\r\nI placed the PSU outside of the enclosure, but it still gets extremely hot, especially during the Summer months. So I decided to use a 5V USB fan to cool it down.\r\n\r\nSince the PSU is positioned vertically, I came up with this custom mount to place the fan near the PSU while occupying minimal space possible.\r\n\r\nI've been using a 120x120x25mm USB fan because it's extremely quiet and provides sufficient CFM to cool down the PSU effectively, resulting in a noticeable difference in temperature at touch. You can use 12V or 24V fans, but they may not be as silent.\r\nCurrently utilizing this creation: <a href="https://www.thingiverse.com/thing:3371050"> Prusa MK3 PSU FAN 120 mount </a>\r\n\r\nHowever, since I also have 80x80 fans lying around, I decided to create this mount just in case and because it occupies less space.\r\nI simply didn't print it yet, which is why I don't have any photos of it.\r\n\r\nMaterials required:\r\n\r\n- <a href="https://pt.aliexpress.com/item/2-PCS-LOT-GDT-80mm-80-x-80-x-15mm-8015s-5V-2Pin-Cooling-Cooler-DC/32379059781.html"> 80 x 80 x 15 mm 5V USB FAN </a>\r\n- 2 M4x30 machine screws\r\n- 2 M4 nuts\r\n- 5V USB PSU (regular phone charger)\r\n\r\nBe cautious with the size of the screws because they may collide with the PSU.\r\n\r\nDesigned in SOLIDWORKS 2019, but it provided a variety of other formats so you can import and modify it to your liking.
