It may have slipped out of my memory, but I do not remember if anyone has published or linked an STL 3D-printable model, of an enclosure fitting:
a Pi4,
a 5 inch DSi capacitive touchscreen display,
a Hifiberry DAC + ADC audio hat.
I am planning to recycle components from my pre-upgrade V5 in a further portable Zynth, both as an FX unit and backpack synth station. Therefore, it should also allow space for a (precious) V5/Pi4 Zynthian thermal block.
I have searched printables.com and other open/free 3D models repos for a suitable solution, but haven’t found anything useful.
Check my fork of zynthian-case. Inside you have branch MINI_V2 with stls for mini v2 pcb for different rpis. You can connect hifiberry to mini v2 pcb hat. There is also freecad file that you can use to adjust the case design to what you need. Mini v2 pcb can be used with 5” dsi screen.
It was for rpi 4 and for 4.3” screen but can be easily updated to 5”. It was few years ago and it was designed using openscad. I remember assembling and it was hard. Too many cables coming from panel connectors back to hat or rpi even though I used my miniature pcb that expose direct connectors for midi, encoders and audio.
When assembling this case I attached miniature HAT to display and than all cables from panel connectors and encoders to HAT so that this can be done without RPI and bottom part being in your way. Than I attached rpi to bottom and attach short ribbon cable from RPI to HAT and finally screw bottom part to top part.
@stojos’s is MUCH nicer than mine… but you need a great printer… unfortunately I don’t have a great printer and printing a single piece with supports wouldn’t come out well…
Top does not need many supports. Just few small one for panel openings. You print it face down. It just takes ages if you have slow printer. Also adding a brim in printer slicer is important to avoid warping of the large part.
Yes, the skirt… since I used the rough print bed I have no more problems… with the glass one I used the Dimafix and therefore I have never used the skirt. Which Slicer do you use? Which printer do you have? Thanks
P.S.
Open Scad?
I use Fusion 360 which is free for personal use.
I stoped using openscad and use now freecad which is totally free.
My printer is elegoo Neptune 4 with open source klipper firmware (not the klipper version that came from vendor). It can do speed up to 500mm/s but I slice my models for 250mm/s speed. I use orca slicer.
Thanks @stojos and @Lanfranco for your prompt suggestions, and your readily available 3D models. Both are nicely designed, and I plan to try the two solutions. I am still looking for the most suitable open/free CAD platform for 3D printing, and while FreeCad is a clever app, it definitely strays quite a bit from my acquired CAD workflow.
I like the idea of having a smaller version of Zynthian, I’m also looking to design a computer set (Raspberry Pi 4 Form Factor) and HiFiberry DAC/ ADC Pro Interfaces…
My main problem is that I’m using as base a Radxa x4 ( x86 sbc) and that the interface of the 40 pins is electrically connected to an RP2040 so I think there are no direct i2s pins to work with…
You may wonder why I am reinventing the wheel if Zynthian already has a software ecosystem and binaries in ARM for the Raspberry Pi so well optimized, supported and polished… Actually I’m looking to recreate the original Bebox usage experience from 1995, and the only way to run on modern hardware is with Haiku (x86) and currently the support on ARM is not at all stable or at all usable.
Perhaps I should open my own thread to discuss it with the community
, this must definitely be you, since I seem to recognise the wooden cladding of your music room! Is that right? Congrats 
and thank you!
. I will get back to browsing you interesting Mini V2 repository!
