Cheese case for Raspberry 2 and Hifiberry Amp2
Optimally passively vented 3D printed case with a hole pattern inspired by a fruit company:-) In “unibody design” of course.
I designed the case from scratch in Fusion360. During design I used your 3D model of the amp2 (https://www.hifiberry.com/wp-content/uploads/2019/07/hifiberry-amp2-1.0.1.step.zip) and a raspberry pi 3D Model from grabcad (https://grabcad.com/library/raspberry-pi-version-b-1).
I also used your Pi holder step file (https://www.thingiverse.com/thing:3821705) and modified it for my need.
Thanks for the step files!
The file “Cheese_case.stl” is the main body of the case. It can be printed without any supports and the design is optimized for 0.2mm layer height and 0.45 extrusion width. For a better finish of the bottom holes, use supports from printbed – you can spare the hole for the switch from supports as the the bridging layer of one layer height makes the use of support unnecessary and can be broken away easily after printing.
The file “Cheese_back.stl” is optimized for the raspberry pi 2 and prints without any supports. Same settings otherwise.
The file “Cheese_holder.stl” needs supports from the build plate.
I printed in PETG, my Slicer said 150g of filament are needed.
