Thing-A-Week 2020: Week Five: D&D Ruins for 3D Printing (Part 2)

I've challenged myself to create a 'Thing-a-week' every week this year, just as a way to keep my skills up and also to actually get some things done. These are little projects & experiments trying out new things, or creating something that I need elsewhere.
I will be putting a full write up of each at www.knightfall3d.co.uk
