This is for 600ml can given with brush cutter or similar 2 stroke engine products for mxing fuel and 2t oil. There are 2 ways to print this.

Recomended way. Print the base and the funnel top seperatetly and stick them together after aligning the funnel head to the bottle.

You can also print the full copy but in that situation I cannot guarantee the funnel head postion to be in the right way.

Also you have can give a small tolerence while printing.
