Ống Thông Hơi Ngực Gundam Cho Worker Harrier

In "Gundam Chest Vents for Worker Harrier", the author mentions using a P1S printer with an AMS unit.

Personally, I used supports and printed it flat side down, but the supports go under the vents and are very difficult to remove.

I suggest angling the whole thing so that the vents print mostly vertically. If done this way, you should only have supports on a side that isn't seen (albeit a lot) and are fairly easy to remove.
