2015-03-02 (M) Prismatic Stereoscopic Screen Viewer

The post on the base for keeping the other pieces in line was moved so that it was flush with the side. This was done by moving it 1/2 of the gap width out on either side. The dashcam bolt holes were expanded 1mm by adding 0.5mm to the radius. After the changes were made to the file the design was reprinted.

A square file was used to widen the grooves in the middle and top pieces which resulted in smooth sharp corners. Each piece fit nicely and aligned well. The dashcam bolt fit easily but was suitably snug. The dashcam bolt was left in place to test the spacing of the unit which fit into the camera adapter nicely.

 A 1/4-20 tap was used to put threads on the camera bolt hole. The ABS plastic cut very well and left clean threads. A fully-threaded bolt was passed through the 1/4-20 threads and a coupling nut was put on one side. On the other side of the adapter the dashcam thumb nut was attached and tightened. The resulting piece was a clean looking adapter.
