This is a makeover from the smooth original https://www.thingiverse.com/thing:2839586/#files
Now with safe air vents (TL-Smooters are getting hot) and some other improvements such as self closing lid and things to hold the smoothers in place when lid is closed.
Because I think smoothers only have an effect on the X and Y step-motors I added an enclosure for 2 X TL-Smoothers.
Oh and if you think those air vents aren't sufficient? Try breathing trough it! You will be amazed!
Happy making and please share your makes and I like getting a Like in return for my thing.
