Storage options under RadRunner/RadRunner Plus rear seat?

[LateNighter]

Has anyone found a good fabric zipper storage or some sort of storage to utilize all of the space under the rear seat on the RadRunner or RadRunner Plus?  I found this linkhttps://www.thingiverse.com/thing:3968884  in which he has 3D printed his own drawer which looks interesting but I think it could rattle and I would rather look for other options.  I am just looking for something that could attach to the frame under the seat and maybe have a side zipper in which we could keep small supplies for the trip.  Thanks!

If I had a 3D printer, I'd make one that fit tight and followed the curve of the wheel on the bottom. Interior would be padded, and an adapter would convert the seat to a hinged cover. The other option is to make it open to the side like a glovebox. Darn, now I want a 3D printer!

I did find someone on Reddit who used a storage bin that was modified.

And here is a really nice one made from aluminum. In my opinion, this one is the best, and it could be replicated in wood. I would have been tempted to leave it unpainted though.
The person gives the dimensions, and also gave his Facebook and Instagram contacts if you want him to build you one.

i tried several iterations of hand fabricated below rack storage options for my radrunner 1.

kydex, plywood, aluminum and coroplast were some of the materials i tried.

no matter the high-quality fit and finish of the storage options i made there was no way to eliminate all rattles short of wrapping all contents in foam or similar.

i even tried a fabricated storage bin made from 1/2" packing foam sheet...which worked best for eliminating rattles but likely had the least longevity.

Go over to the Radrunner area and see what I have done, pictures are included over there.
