Fiat Doblo Maxi / Opel Combo trunk door inside lock safety plug

Even when I lock the car from the inside, the inner lock of the trunk can open the trunk door. I was afraid my dogs could accidentally open it, so I printed this safety plug to make it impossible to unlock the trunk from the inside accidentally.

It is still quite easy to pull the plug out with your fingers in case you want to escape the car through there yourself.
