Since I uploaded the YouTube Shorts featuring my 2018 MOC of the Justice Palace, I’ve taken the time to create brand new PDF instructions for this model. You download it on Rebrickable and on Patreon for free!
Also, if you’re interested, you can take a look at the video instructions I made for this model a few years ago. Be aware that the software I used back then wasn’t as advanced as Bricklink Studio 2.0.
LEGO Digital Designer was a great tool for me back then and had an amazing building instructions algorithm (with some clunky gimmicks from time to time) – but it did the job pretty well!
