Safe Storage for Counting Chambers - tested (Fuchs-Rosenthal, Neubauer hemocytometers, etc)

thingiverse

Counting chambers are expensive and tend to get scratched up after a while. This should help with the latter. Holds 8 hemocytometers. 2 Versions: In version one, I tested rounding of the edges using the minkowski sum with a 1 mm sphere. See scad file (but beware of long render times when using the $fn function). This version must be scaled larger during slicing (ie 110%; as all walls become wider) The second version omits the minkowski sum (however rendering at $fn=180 works with this version). Print it yourself or order from my Shapeways shop. Currently I have added the second version only. http://www.shapeways.com/shops/leanlabs
