Modeled and rendered in Blender 2.83.4 with Cycles render engine. I intended for the shader to look like an SLS 3d printed object. I think I got a decent shader started, but I can see some areas which could use a few tweaks to make it just right. The model itself is, in fact, modeled to scale in mm and capable of being exported as STL for 3d printing on an SLS or extrusion printer. Thickness is 1.5mm, and overall dimensions are just over 30mm on all axis. I modeled a US quarter coin to scale, which is roughly 24mm in diameter and 1.7mm thick, as a size reference in the render.
