Okay so here's the start of a WIP from start through to finish.
This is a pic of a 2d lasercut I made with Inkscape. Surprisingly easy to get the hang of as I've never used a 2d CAD type thing before.
So this shows the staircase in all it's smaller parts, step by step, if you will excuse the pun. They will sit on top of each other glued together. I'll then add some puttywork over the top to make the stone.
The other odd looking pieces are wall sections, they are designed to fit together. Whether it works out like that or not is still to be seen


I'll be puttin up work wip shots once they have arrived and I've assembled them. Then puttied and finally molded and cast. That may be a while as I only have a small amount of molding rubber left and don't plan on spending a huge amount until the end of the year. Saving for xmas already.
forgot to write: I increased the cut line size so it's easy to see. usually it needs to be 0.01mm wide. And that's no typo.
