I just bought my first set of heat-set threaded inserts from CNC Kitchen and wanted to practice with them as I had never used them before.

I created this test model that fits the 4 smallest inserts: the M2, M2.5, and both the short and long M3. The holes start with the small M2, then the M2.5, then the DEEP M3, and finally the short M3 at the opposite end. You can refer to the image for reference - the screw driven further down is the full-height M3. A measured drawing is included in PDF format.

I hope this helps others practice and test these. Note: screws not included. 😉
