Seestar S30 Pro Lens Cap

I created a lens cap for my new Seestar S30 Pro. I found one on Printables but i did not like the fit. There is just enough clearance 1 to 2 mm when closing (see pictures).Made on OnShape:https://cad.onshape.com/documents/435b20853dea2a3d477bbf70/w/9036ab508218a362e1a461dd/e/4d50e1131ecc6f08b36c1df8?renderMode=0&uiState=69c458cdcc856ddf5015b164
