Here is the STL from befinitiv

thanks @finis-dev
however, this doesn't look exactly the same like the version from above screenshots (abobe, the raspberry can be inserted in diagonal, and we can see holes for usb ports and hdmi, as well as inserts for screws to close the enclosure)
It's always interesting to see people continue a project on the original developer's idea, but then not share their progress (for others to then progress with) with those that also want to progress this project.
It's not like there is money to make with this anymore, or to patent it. Super-8 is very niche, and a patented marketed Digital-8 cartridge already exists. It's just kinda expensive.
hey please if anyone is working on this project still please contact me im having trouble here installing the picamera ... i am now trying picamera2 but I'm not sure what's the issue unless someone would want to share there SD card. The rest of the project is complete in housing with everything.. im just stuck with the software issue

ok its working i think im no longer getting errors and im running Bullseye. The camera is showing a small red LED when running the script now im trying to see the live feed from my computer via web browser and nothing .. i had tried changing the ip address to 192.168.1.117:5000 but that didnt change anything considering the PI is on that address already @antisaint81
actually i believe the issue is i haven't set up the
[camera.service]
(https://gist.github.com/befinitiv/fd44a597a48460c100a54649c97d5984#file-camera-service) where would i implement this..?
yep, doesn't look like the STL file will be shared by @finis-dev :( that would have been a nice "xmas gift" :D
