I needed an enclosure that would not be a permanent fixture in my garage. This allows me to quickly remove the enclosure once I am done.

I am going to be upfront, I do not write instructions too often. So, please don't hate too much. I will attempt to clarify any questions as best as I can!

Lastly, I recommend that the control box for your printer not be placed in this enclosure while printing. It is designed to keep warmth in.

Bracket Information:
You will have to print 4 of each file

The upper corner brackets are designed to hold 1" thick insulated foam board. If a different size is needed, please post in comments and I will do my best to change this.

File Explanation:
Inner Corner Brackets (FIG 1) - These are taller than the outer brackets. This allows you to position the foam board quickly (positive feedback once you hit the taller wall of the inner bracket).

Inner and Outer Brackets (FIG 2) - I used two (2) 1"-5/8 long wood screws per bracket to secure. You can use more if you want, but it is not needed. I put multiple holes in the brackets to allow you more mounting options if needed.

Upper Brackets (FIG 3) - No special hardware needed. I recommend cutting out the side walls to allow the brackets to recess into the foam board a bit (FIG 4). If you do not do this, you will have a 1/4" gap between the ceiling and walls (FIG 5 - shows what you should see roughly).

Sealing Gaps - There will likely be a little gap between the sides and ceiling. Once again, this is a temporary enclusure. I simply use masking tape to seal these small gaps as it pulls the foam board together.

Enclosure Assembly:
This is user determined based on what you're trying to enclose.
As an example, if you wish to create a 25"x25"x25" enclosure (using 1" thick foam board)
1) Left and right walls will measure 27"L x 1"W x 25"H
2) Front and back walls will measure 25"L x 1"W x 25"H
3) Ceiling will measure 27"L x 1"W x 25"H
4) You're likely wondering how you can see your print during this... I would cut a hole or a square in the front wall. Then get a piece of plexi glass and tape this over said hole or square.

Mounting of corner brackets:
1) Cut out two small pieces of the material you will be using. These only need to be like 2"x2"xthickness of the material you are using. These will be your templates so you can screw down the inside corner brackets quickly without having to measure. (Fig 6)
2) Mount one outside corner bracket
3) Mount an inside bracket at this same location. Use the templates you just made!
4) Measure out the distance to the next corner bracket you wish to install
5) Mount inside corner bracket using the templates you made
6) Continue this till the last two corners are mounted

Bill of Materials:
4 foot x 8 foot insulated foam board - This can be found at most large home improvement stores (Lowes, Home Depot, etc..). It roughly costs $10 - $15 (USD) per sheet. Depending on the size of the enclusre you want to assembe, you may need more, or less than this size. I used a 4x8 sheet (a majority of it) for my Tevo Tornado.

Small piece of plexi glass (viewing window)

Screws - User dependent (I used a total of 16)
