You’ve heard the fear mongering stories that people now have the capability to print a gun at home. Whilst this should still be your primary fear, 3-D printing is going to affect the nudes you send as well.
Women now have the capability to print out your unsolicited d*ck pics, now when they are exposed it won’t be the picture with camera trickery that you sent. Your d*ck pics can now be printed using a 3-D and can be shown in their full unsolicited glory.
If you don’t want to be the laughing-stock of a girl’s group chat, remember it’s 2018 and technology is not the same as it was before. The only good thing is that 3-D printing takes hours so you have head start to do damage control.
