Making tube display assembly

Display holder with red plexi. made of 20×20 aluminium L shape, posts for plexy turned on drill 🙂
Main problem was to find out an angle of tube sockets as these tubes were not manufactured with precision, like some later models.

After assembly of L shape aluminium profiles I attached 10 x 60 mm posts with M4 threaded holes. Cut A4 perspex to size by Stanley knife from both sides and snapped. This creates nice accurate edge. Then use puncher and drill 2, 3, 4 mm to drill hole of desired size. Persex is much easy to work with then I thought.
