Packout Parasite

A simple tie-down point for adding a couple extra items onto your Packout for a free ride.
Perfect for an insulated highball cup, a pack of smokes, or whatever.
The shoe fits freely enough to slip on and off easily, best for vertical carriage. Strap it to your desired item and drop it into your Packout lid.
The eyelets are conveniently sized for a bit of 3mm shock cord or similar sized paracord. Add a line-lock for adjustability or custom-size the cord for your desired item.

I suggest using support blockers to create 100% infill for the eyelets and the root of the "shelf" for strength. The rest of the Parasite is fine with 20% infill or so.

Included are two sizes, one with a larger shelf and one with a little shelf. The shelf size and thickness is the only difference between the two.
Also included is the FreeCAD file if you'd like to customize to your specifications.
