Feet for CTC, Flashforge and similar

This thing is a foot for a CTC, Flashforge or similar 3D printer. You need 4 of them.
It can be used just with some kind of "grip pad", but I recommend to use additional case feet if available.

I got my case feet from the german online shop pollin "http://www.pollin.de/shop/dt/MzM0OTU1OTk-/Bauelemente_Bauteile/Mechanische_Bauelemente/Montagematerial/Gehaeusefuesse.html" item id: 440 566. Alternatively you can buy it here: http://www.ebay.de/itm/like/141197278435?lpid=106&chn=ps&ul_noapp=tru
