Blank Filled Insert for Rugged Multipart Pinecil/TS100/TS80 Case (V2)

I wanted to make a few new inserts for the excellent case by @PjotrStrog, but could not find a simple blank insert I could subtract insertable items from. So I measured a bottom large insert, created a cube of the measured dimensions, added a fillet and a chamfer. The original (non-solid) FreeCAD model is also available.
