The title says it all! Made this so I could have some cool, unified-theme bases for my Table-Tactics force. Its 25mm wide and 3mm tall (not counting the plank texture), the same dimensions as your standard lazercut MDF bases. I made it in those dimensions as the MDF stock is usually what I use for my pieces, though with a little tweaking you could make it beveled, raise it a little, square, whatever you need.
Printed in Sea Green ABS at plate/extruder temps of 110/230, 100% infill and a .10 layer height. Shown with Reaper model for example/size comparison. Painted with water based acrylics.
