Raspberry Pi 2 Stacking System

thingiverse

A versatile cradle system for the Raspberry Pi 2 & Raspberry Pi 3. The design cannot be classified as a case, given that it does not include sides or a lid. Assembling post-printing is straightforward; simply stack additional bodies with Pis inside them. To link adjacent cradle bodies, you will need to print two separate links. A friend requested that I print redogre's Pi 2 stacking system, but since the link was integrated into the main file, it would not fit on my Vector 3's build plate. The solution was simple: split the model into two files. RaspberryPiStack_Body_v3.stl is all you need to print to build a tower of Raspberry Pis. This updated body features stronger attachments to its columns and some geometry fixes to eliminate slicer anomalies observed earlier. pi2stack_body_v2.stl is also used for building a tower of Raspberry Pis, featuring an updated body with stronger connections to the columns. pi2stack_link.stl can be used to link adjacent stacks of the body together. Note that the original pi2stack_body.stl file had weak links between the base and the columns, which were prone to breaking. I have created a more solid version; pi2stack_body_v2.stl with strong connections. A larger resolution image of the finished cradle is available on my Flickr, as well as one with a Raspberry Pi 3 mounted in it. Print Settings: Printer: Vector 3 Rafts: Doesn't Matter Supports: No Notes: Do not use supports, as they will block the stacking mount holes. I printed mine at 0.10 mm with green PLA. How I Designed This: Splitting The File Into Separate Parts I took the original design and imported it into Sketchup, deleted the link, and exported a new STL. Then, I repeated this process to export the link to its own file. After printing and finding that the towers broke away, I checked the slice details again. Noticing the lack of connection between the column bases and the cradle, I went back to work. Better Connecting The Columns I switched to X-ray mode in Sketchup and noticed some strange geometry around the towers. Once I deleted some spare lines, a newly exported STL showed a better-looking corner with stronger connections between the column bases and the cradle. Then, all I had to do was repeat this process a few times to correct all four corners. Now, the slicer brings them out as solid. I have attached my SketchUp files: RaspberryPiStacker.skp and RaspberryPiStacker.skb.
