Regarding the "no instructions provided" review: true but a bit harsh.
1) Those are just boxes, if you look at the pictures on the store, it's pretty much self explanatory and very easy to replicate with so few parts.
2) You did not ask any questions before posting a review? give the makers a chance to help!
3) You can do it! It's extremely easy. As soon as you print the parts, it will be obvious this is the front, sides, back, decorative parts, etc.
4) Look at more details pictures in the individual cases for sale. This is for the bundle. Like this one: https://www.cgtrader.com/3d-print-models/hobby-diy/electronics/sgi-crimson-jurassic-park-pi-case
Thank you.
