I test fit the ejection port front and back together, when I pulled them apart the pegs snapped off of the ejection port front. I did not want to spend another 7 hours printing a new part so I made these pegs that will help hold the 2 parts together.
I cleaned up the peg area to make it level and smooth (see pic) then these friction fit in the opening. You can glue for more permanent fixture but should not be needed.
I printed this with 100% infill and a brim to help adhere with it being such a small part.
Hopefully this helps someone else out that runs into this issue.
The author remixed this model.
Just made pegs from it that could be used to replace a portion that snapped off.
