I believe this happened to someone else recently. If a replacement isn't already available, I will model something and put it up on shapeways. Might not be till tomorrow.
Edit: Or now, I guess.

There is a tiny cosmetic detail that I didn't add. For a piece so small, I didn't want to compromise its solidity. I hope it works. I measured the piece on my v2 VF-25F with a digital caliper. I did not test fit. Mine is not broken, and I want to keep it that way. Let me know if it fits. If it doesn't, it wont be a big deal to revise. Took me 5-10 minutes for this one between walking to my computer to uploading.
Test print on my FDM printer. Looks like it should work.
