Printing a case for Raspberry Pi 4
I was going to chase it around the desk uncovered, and then I though I would design one and 3d print it – I was thinking of something with the board on its side and a chimney to help cause a breeze. As I have never seen a pc case with a chimney, I suspect I was setting myself up for failure….
Anyway, then it it occurred to me that some kind soul might have already contributed one, probably without a chimney, to Thingiverse, and it transpires that several folk have been generous.
Almost arbitrarily I have chosen a design by Malolo. This contributor has actually uploaded a whole bunch of mix-and-match parts that can produce, for example, a most wonderful-looking one where the Raspberry Pi logo is the case vent (image left). However, as I only have black filament, I chose one with lots of hex holes in the top and bottom surfaces to allow as much heat as possible to escape.
BTW, several contributors are offering cases with 30mm or 40mm fans. This one by Bigjeffrey (right) adds a 30mm x 7mm fan to one of Malolo’s plainer designs and, according to Bigjeffrey, “Raspberry 4B 4Gbyte is heating up to ~62°C in idle without a housing. By adding a 30mm 5V fan, I was able to reduce its idle Temp. to ~42°C without using an additional heatsink”.
Some time later – the completed case with stand. Surface finish is not great as it is printed in PETg for heat-resistance, and hot (240°C) for strength. It would look a lot nicer – matt rather than oily – in PLA printed at 195°C, and maybe in colour other than black.
I am still getting a lot of thick strings with PETg, although none with PLA – despite the hot PETg profile passing the bartoaster/Loohney stringing test with flying colours.
Hopefully, the postman is delivering the Raspberry Pi to go inside as I type.
Hats off to Malolo’s creative talent.
And, excuse my awful photos – phone camera, poor light, black object…
