Printing Job - Mthatha, EC, 5100

Good day, I need something 3d printed, make 2 quotes using acrylic and plastic. This will be for lab use, in fact I am trying to replicate the Sedgwick-Rafter slide for my research to the nearest accuracy possible. The most important part is the counting chamber which has these dimensions 50mm x 20mm x 1mm (length, width, height), eventually a volume of 1ml. Furthermore, the counting chamber base is gridded with 1000 1mm squares. Then all this if fixed on the center of a slide. For the purposes of flexibility, the dimensions of the chamber can be changed except the 1mm height, also the number of grid squares can be changed along with their dimensions. Now I will also need a cover slip which will close the chamber, thus must be a bit larger than the chamber.
