Audi/VW plastic captive nut

This is a remix of SpectreGadget's original mount/nut (https://www.thingiverse.com/thing:703543) to accommodate different screws/bolts.

A modified VW/Audi part no. 811807577C.

Aftermarket boot/trunk grocery bag hook kits (eg. https://www.amazon.co.uk/dp/B01EYQ19QY/ref=cm_sw_r_cp_ep_dp_LsEAAbNVH7GXG) for Audi don't fit the A5/S5 coupe. The hooks I received came with M5 x 20mm hex socket cap head screws, which were too long for SpectreGadget's original mount. So this remix includes 3 different bolt/screw options using both the longer M5 and other common screws:

• 4.6mm through hole suitable for M5 (5mm) screw
• 3.0mm through hole suitable for 3.5mm (No. 6) self taping screws
• 2.5mm through hole suitable for 3.0mm (No. 4) self taping screws

I performed testing on various hole sizes and print orientations for strength and durability in PLA. Printing upright causes a weakness in the "legs" which can cause them to snap when pressure was applied inwards. Laying the part flat lines up the layers along the leg allowing some additional flexibility. The part has been modified to lay flat so no support is needed.

No testing has been carried out in other materials.
