Stack Exchange — 3dprinting.stackexchange.com
The content of 3dprinting.stackexchange.com (https://3dprinting.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 40,797 rows: 15,283 posts (5,735 questions, 8,905 answers, 320 tag wiki excerpts, 320 tag wikis and 3 posts of type 6) and 25,514 comments, written between 12 January 2016 and 31 March 2024. Beside it are 33,730 user accounts, 56,355 votes, 34,000 badges awarded, 496 tags, 52,303 post revisions and 1,581 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 43 rows.
