*Update from Apollo on the 3D design and printing* I have designed the prototype base and pi mounts in Auto desk fusion 360. The picture below shows the part in Fusion 360 and in the slicer program Cura (3D Slicing Program). I have already printed a pi mount to test the clearance between the 20 mm extruded aluminum and the mount. 20.3 mm square is the exact needed so I ensured the base matched. I also added holes in the base on the bottom to allow weighted items to be placed in the base. So far I'm up to 3 designs and 4 prints needing to be finished. The Printrbot simple metal is currently hard at work on the base of the scope. I should have a good physical prototype later this week. Though a large hurtle of designing a reliable lens mount is ahead still.
