This is a spire structure I created for small scale wargames. The base is 55mm x 55mm which fits neatly on the foundation spaces in Monsterpocalypse. This terrain piece is intended for personal use only and not for re-sale.
Edit: Several folks have expressed frustration printing my models on SLA printers. Chitubox in particular will not slice my models correctly. After some research and help from my friend we found a solution. We brought the model into Prusa's Slic3r first and exported the plate as a STL file. We then brought that STL file into Chitubox and it worked each time. I hope this helps you if you've experienced this issue.
