Porthole for big

I needed a bigger porthole, so I sliced down this neat design to four pieces. This size holds a 26cm diameter glass. Bolts and axles not included, they must be printed at 198% scale to fit.
The "porthole tube.STL" is for filling space in drywalls and such, scale as needed and print 4 pieces.
Sand contact faces and superglu them.

I promise to upload pics when finished.
