Porthole for big

thingiverse

I required a larger porthole opening so I dissected this clever design into four separate components. This size accommodates a 26cm diameter glass insert. Bolts and axles are not included, requiring printing at a scale of 198% for proper fitment. The "porthole tube.STL" file is designed to fill gaps in drywall and similar surfaces; print the four pieces as needed, then sand the contact faces before supergluing them together.
