I really like the concept of logan's well-known Extended Case. This is my spin on it to fit a few extra design criteria:
* All sides should fit on the
...Show more Tarantula's large printing bed (28x20cm) with no gluing of two halves required
* Enclosure needs to hold MKS board, power supply, discount display, and a mosfet board
* Lots of air flow! 120mm fan desired
* Case should generally be as small as possible, preserving all above requirements
This design I've made achieves all this, and I think it's an ideal choice to give the Tarantula a sleek and tidy look.
Required Hardware:
Like logan's design, you'll need plenty of M3 flathead screws (30 or so, here's a cheap [pack of 100](http://a.co/1WKMi8p)), at least 12mm in length. I plan to use [brass inserts](http://a.co/gSS68iO) on mine to keep the threads intact, but you can tap the holes instead. The enclosure is also designed with a 120mm fan opening on the top, and I ended up using a fan filter inside to A) keep dust out, and B) make sure no wires clipped the fan blades by accident. I'm using [this fan](http://a.co/02WARBm) and [this filter](http://a.co/4GiLybe) for the project. I wholly recommend using a filter because it will keep wires from potentially hitting your fan blades. A [C14 socket](http://a.co/2STb20s) will also be needed in back; if requested, I can put out a version with a round hole in the back instead of the socket, in case you'd prefer to stay basic with the power wiring. Oh, and a power button! I am still deciding what power button to implement, but as it stands, the hole is 16mm in diameter. My plan is to use [this switch](https://www.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=259848097&uq=636609766513526043), however it is $7 because it has that barrier to keep you from bumping it. Cheaper switches can be found, such as [this guy](https://www.digikey.com/product-detail/en/cw-industries/GRB049A05BB1/SW647-ND/2235519).
I attach my MKS board to the top of the power supply; all I did was drill four 3mm holes where I wanted the standoffs, then screwed in the bolts. Holds steady and there has been no strange electrical behavior (shouldn't be, since the power board chassis is ground).

NOTE: If you are planning to do this print, hole sizes may need to be adjusted. Message me if you need any more info. I am doing this print in the next few weeks, so I can make sure everything is perfect after I have completed one test run.
