Modular castle kit - Lego compatible

thingiverse

UPDATE (Feb 2017): This version is deprecated. If starting new, use http://www.thingiverse.com/thing:2141175. Assemble Lego-compatible size blocks into a large medieval castle. You choose: print bricks with base platform attached, stackable objects on top of a base plate or combine both. Objectives: reduce print time, encourage creativity (kids can adapt and expand with their own bricks), easy to print, sturdy and expandable by those with minimal OpenSCAD skills (create your own blocks). Print a single castle-tower.stl for starters; by Christmas, you should have a reasonably impressive set. File types: bricks with flat bottom (easier to print) are default; stackable objects can be placed on top of base plates or other pieces. Some files use a larger 16x16 base plate. Slicer settings: Layer size at 0.25mm, speed 12-20mm/s for first layer, 40mm/s for perimeters, fill at 0.25, three fully filled layers for floors. Difficulties include bumps in the bottom layers, base layer not sticking, ugly bridges under horizontal overhangs, and warping. Printing multiple pieces at once can also cause issues, as can printing stackable base-plate pieces. Post-processing may require removing stringing or filing corners. OpenScad code is available for use and customization. Ideas for castle assembly are provided, and file netfabb can be used for planning prints. Print aborts can be assembled and burned with a mini gas torch to create destroyed castles.
