A very simple set of keyed ribs and spine segments which can be used with clear poly to create a MicroGreenhouse dome over a section of plastic gutter.
The spine segments are numbered. Attach the ribs, then orient the segments numerically. This will ensure optimum spacing between ribs.
I’ve noticed when the ribs are printed with PLA they will delaminate fairly easily when flexed. When printed with ABS the ribs are more robust.
