About this 3D model
UPDATE VERSION: https://makerworld.com/en/models/1435312-blank-keychain-tag-thin#profileId-1493133 (this is a thin version) I liked the original keychain, but they didn't have a blank tag on here. I brought their tag from printable over here, but I cut the very top layer so it would have a flat top. The original one had some indent. Anyways, you can use the letter feature to add labels to the tag.
