Picatinny rail to Nerf rail adapter (reverse adapter)
thingiverse
I searched the entire Thingiverse and it seems that no one has made such a thing! This is an adapter for attaching Nerf attachments to Picatinny-style rails on some brands of toy guns. Or if you want for some reason, to your real gun as well (untested)! There are two sizes of the adapter, the upper one is narrower, the lower one is wider by 0.5mm. This is made to fit the pictured toy gun tightly so your mileage may vary depending on tolerances.
