Rear Sling Hook for PDW Buttstock

I made this rear sling hook for my SA-H04 and SA-H07 airsoft replicas of HK416C PDW guns. 

For righties it is advisable to turn the loop to 01:30 position (from the aiming position), between the bolt assist and the charging handle, while lefties should turn it to 10:30 position.

The ring is 4mm thick, so you really should get a bit longer screw, or otherwise you might damage the threads.

Printed in nylon (PA) with brim and 90% gyroid infill, making it very sturdy. When printing objects in nylon, you should see how much it shrinks in horizontal and vertical axes, so before printing scale the model up for that amount. The one in 3MF project file is scaled up 3.6% in XY and 1.01% in Z axes, while the STL is in the original scale.
