Mason Jar Polysmooth/PVB Chamber

This was just a prototype but it works well enough that it is worth sharing. I used this fan here. Unscrew both meshes, take the screws out of the rubber inserts, and use them to fasten the fan to the model. Make sure the cable goes through the lip in the lid. The lid should be a relatively loose fit on the main chamber for safety reasons.

Now all you need to do is add a stand at the bottom for prints and insert some IPA or a paper towel soaked in it. Put your prints in and let them smooth with the fan on (supervised of course). 

NOTE: I don't know if this works with acetone! Use it for acetone at your own risk!
