AMS 1 replacement rear silicone plug

Bambu wants FIFTEEN DOLLARS for a replacement AMS seal and rear silicone plug. That's highway robbery! So I took one for the team, bought one, and then modeled it.

My printed version - printed in TPU - fits perfectly where the OEM one was. TPU is quite a bit firmer than silicone and it lacks the adhesive ring so it's probably not as good as the official replacement, but for 10 cents of TPU, it serves my needs just fine!
