Poor man’s enclosure

aka heated chamber, heated room

Another problem with ABS is the fumes. My Mendel extruder seems to give off more fumes than HydraRaptor's does, perhaps because the melt zone is much bigger, and the white ABS seems to smell more acrid than natural ABS. I did a build with a window open to get rid of the fumes but most of the parts then warped, presumably because there was no longer a buffer of warm air around them, but a cool breeze.

In an attempt to tackle both of these problems I built an MDF box around my Mendel.

In my case everything I’m working on is “experimental” and in the process of rebuilding. What was needed was a method to grow with my projects. The answer was simple. Build an enclosure out of clear plastic aka "Visqueen" film. Thick enough to do the job and hold up to use.

Lightweight, flexible polyethylene construction film offers economical all-weather protection indoors or out. Known as "Visqueen" film - a brand name, although this is a commodity plastic product.

Some quick thoughts/ideas:
1) Make a front folding flap and install a couple of magnets to lock the cover when U need it closed.
2) Your stepper motors produce heat, cool them and reuse the heat. Install a fan blade on the unused shaft side,FREE cooling/reuse heat. Many sub-ideas can come off this simple idea.
A) Like the back and forth of the stepper could be used to make a one way fan.
B) The free air movement can be used to vent out the fumes.

Give me some links with your projects off these ideas. Would enjoy seeing them!
