** Update 2023-05-22 **
I've added a second, alternative version, of the left-hand part of the model to accommodate an internal floppy drive. Note the right-hand model is unchanged.
The mounting points for the Pi have moved further into the centre of the case and the Pi needs to be rotated 180 degrees from the position in my original photos to allow room for the RCA video/audio connections.
I removed the top metal case of the floppy drive so it would fit inside the A1200 case. Cutting the top floppy drive case instead is possible, but I've opted not to do this for now.
An additional parts list can be found below - please note that I've replaced the HDMI cable with a new version with a right-angled micro HDMI plug that works better with the Pi's new location. Right-angled RCA plugs have also been utilised.

Introduction
Inspired by the excellent Amiga 500 Raspberry Pi Non-Destructive Case Brackets created by mattsoft, I was keen to create something similar for the Amiga 1200 i.e., this model enables you to mount a Raspberry Pi inside of an A1200 case without damaging it.
For my project, I used a Tynemouth Software A1200/A600 USB kit which enables connectivity of the original A1200 keyboard via USB to the Raspberry Pi.
Due to the size of my 3D printer (Anycubic Kobra), I’ve split the model into two parts; these take approximately 3 hours each to print.
Print settings
I printed the parts as follows:

Conclusion
I’m sure there are improvements that I could make - I’d be happy to get feedback. Overall I’m pleased with this design, in that it fits my A1200 case really well, and am able to connect modern components such as HDMI and USB easily and cleanly.
