This funnel is for the separation of dried blood samples (punches or nibs) to help with process workflow. It is large to prevent the operator from accidentally putting the sample in the wrong location, or needing to use tweezers to transfer the dried sample over.
The letters to the left and right of each hole denote the well each funnel leads to. Depending on printer settings, you may need to clean up the holes to get rid of any stringing.
Print with line of eight holes facing up. Organic supports are recommended, but should work fine without supports.
The author marked this model as their own original creation.
