Print two end caps, one grid. Inital assembly requires melting the corners of the grid to the outside the endcaps, to give a smooth even edge. 1 - for clearance in the pipe, 2 - to hold it together. 3 - I used hot glue as an additional fastener for the end caps.
This will slide into an 1/5" pvc pipe.
EDIT: added the solar panel mouts also.
