Summary

I got tired of my external HDD moving around and not being secure so I printed this!

I used this HDD caddy: https://www.amazon.ca/Sabrent-Tool-Free-Enclosure-Optimized-EC-OCUB/dp/B07NF6JQQ4/ref=sr_1_20?crid=1QR3PRK8U90YB&keywords=HDD+caddy&qid=1673830798&sprefix=hdd+caddy%2Caps%2C101&sr=8-20

For the screw hole you should use something like this, which I got off an old ebay watercooling kit I ordered a few years back: https://www.ebay.ca/itm/152074546700?hash=item2368596e0c:g:IJ4AAOSwdQ5iHJAz&amdata=enc%3AAQAHAAAA4HBrymHpJ4Qgl%2FCxegiobya2Nu2ugI8RFlyQjDDZ73L3%2FQGJe6rGq2JzWGZqM6mNp%2FJGa7JOxbHfK207d34Eo1a80e7RUYkG98g60f9rXN7Znn1EHDx7qdWhsOJkvo1iXunBuQQ8%2FrvWXDekmD6VywtuC76B%2F6%2BxpJzfx%2BJluCpkzrBWJBax0k%2BIvmt5hxeQjH2uChr7aTePoyKg50%2B9pYLnEFvxdPDCxK8mKi23R07pkMD%2FvdBqBoCj5GAaaLhZIc2FWFdGgbaZ7YZB4sO3aGUXctV5CVI9tQhGm87yjGFX%7Ctkp%3ABk9SR-ycxoG3YQ

It's not perfect but it works.
