I designed this object to slide into the nylon bands found inside the Think Tank Photo FPV Airport Helipak after I found that some of my smaller drivers and other tools were too small to be held tightly by the backpack's nylon band.

Thanks to a “fingered” design inspired by Maker's Muse's video, 3 Design Tips for Better 3D Printed Holes - CAD For Newbies. These fingers hold the tools tightly enough that they're kept from coming loose as I carry my FPV backpack.

My design uses the sector and arc modules found here: Circular sector and arc on openhome.cc.
