Augers

Two 80mm diameter augers for use in r/c trpmmels and the like. Sizes are 200mm or 300mm long - with a 6mm bore 50mm deep at both ends. The driven end of the shafts is 20mm dia while the output end reduces to 12mm to decrease back presure a little.

Both files incorporate a brim to help with bed adhesion, no other printer supports are be needed but I suggest you make the walls at least 2mm thick (preferably 3mm) and use 25% or more infull if you intend to actually use it.
