Holley 4150 style Carburetor spacer for casting
thingiverse
This model is meant to be cast in aluminum using green sand. I have not scaled it to compensate for shrinkage, but aluminum is typically 6% so I will scale in Cura using a factor of 1.06. I plan on milling the surfaces and adding the holes on the mill. My model is 1.5 inches tall, but you can scale it to whatever you want by scaling the Z axis in your printing environment. NOTE: A draft has been added to allow for demoulding, this model will print best with the larger surface facing the bed. (think sandcastle) EDITS 3/9/18 - REV 1 - ADDED ADDITIONAL DRAFT 9/14/18 1ST CASTING ATTEMPT, ROUGH SURFACE AND POROSITY. WILL RETRY.
