4.5mm tube plug

a tube stopper for 4.5mm inner diameter tubes. they are mainly used of carburetors. step file included to adjust size for larger or smaller tubes and here is the onshape link. I printed it out of tpu as it fits better and is chemical resistant. https://cad.onshape.com/documents/4fb0105bfcf4939ce3282086/w/7351511f82b676d4daa67c54/e/02286589543204f42681dc24?renderMode=0&uiState=6812c6f0ab9e1a31e2a3a6a6
