This is a roof spacer for Suntuf plastic roof sheets. I designed this because I couldn't find any parts relating to this specific style of more angular panels, as opposed to the more wavy, rounded panels.
I only needed a couple of these, rather than a full row, to support and tie down some key areas.
*UPDATE* I usually print these on the side, but discovered a major irregularity when printing from the base. I've squared off the base and top, then uploaded the corrected version.
The author marked this model as their own original creation.
