CushionAnchor

Spiked retainer to keep couch cushions in place. You need two of them to get spikes on both sides.The snap-fittings are a bit fiddly and time-consuming to install so you could just glue them together instead, but i wanted to make it printed-parts only, so the option is there. I am considering to make the spikes smaller for a faster print, also some different sizes.
