Pololu Voltage Regulator Case and Lid

prusaprinters

<p>I designed this case and lid in Fusion 360 to mount my Pololu buck converter so I could power my Raspberry Pi 4 from the Prusa's power supply. I tried using <a href="https://www.thingiverse.com/thing:4068417">https://www.thingiverse.com/thing:4068417</a> but it didn't fit the Pololu I actually ended up getting. I designed mine based on that one but added a lid.</p> <p>It seems that the Pi 4 may have slightly higher current requirements so I wanted to get a more capable regulator and got this one: https://smile.amazon.com/gp/product/B01M659ER2/ref=ppx\_yo\_dt\_b\_asin\_title\_o09\_s00?ie=UTF8&amp;psc=1</p> <p>The Pololu board is held on using M2x8 screws and the lid is fastened with M3x10. There are enough of these in the spare parts bag that comes with the Prusa i3 MK3S kit to use for this.</p> <p>This is my second design from scratch ever, in Fusion 360 so It's not great, but it worked for me and I thought I'd share.</p> <h3>Print instructions</h3><h3>Category: Electronics Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> I3 MK3S</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.2</p> <p><strong>Infill:</strong> 15%</p> <p><strong>Filament:</strong> Overture PETG Black</p>
