UPDATE: I tried using the peg the other day and noticed it didn't fit as snugly as I wanted. So I scaled up the peg by 5%, on top. It fits better now. Please let me know if you have any fitment issues. I can upload some different sizes if needed.
This is designed for the Modified YT-1300/Millennium Falcon from the X-Wing Miniatures game. Some of them have a little slop in the post hole on the bottom of the model. This is simply a larger peg to have a bit less slop in there. It's designed to fit into the model only and not into any other posts.
Make sure you use a lot of top layers to that the peg has a few solid layers below it, to connect it to the main column. This should help prevent it from snapping off. That, or just print it solid.This printed in about 30 minutes at about 60mm/s. I used a brim and made it 10mm wide. This was printed straight up and down, not laying sideways.
