DIY 3D Printer Enclosure - No Acrylic, No Screws, Easy Assembly

This is a quick, simple, inexpensive, easy-to-assemble 3D Printer Enclosure to prevent drafts (cold air) in the coming winter months. This is used mainly to prevent warping, which is caused by cool air and thermal contraction of the the 3D print.

Note: please follow and read the instructions carefully. Use this Instructable at your own risk!

Connectable Play Mats - Make sure they are large enough! (The screenshotted one is large enough for my Prusa i3 mk3s)

3D Printer (the thing you will enclose)

Optional: Large Sheet of Cardboard

Use the connector mats, assemble a semi enclosed cube (5 faces). The connections should be made 90 degrees to each other. Don’t worry, the mats are made out of foam, and they assemble and disassemble with just a click.

Do not completely seal your printer inside! More about this on Step 3.

Lift a ‘tab’ to let a wire out to the wall.

Start by printing a test print with high bed-adhesion-area without the door (This may be sufficient if the environment isn’t super cold)

If the 3D print still warps, try the test print with a door (Step 3)

In my case, a semi-enclosed enclosure was enough to produce 3D prints that did not warp.

See video here:

Use a large piece of cardboard to create a non-airtight ‘door’ to the enclosure.

The enclosure is not intended for odor/particle prevention. Warp prevention only.

It is highly recommended that you have a camera with AI print failure detection with this enclosure, since the enclosure is not transparent.

Be sure to thoroughly test the enclosure before using it completely unattended.
