Paperclip

I made a paperclip because I think they are cool.

Create a 75 mm line and 125 mm line under it. Then add a 3 point arc to the end and make 40 mm and R20

Add a 100 mm line then measure is between the 125 m line 30 mm and R15. Add a 20 mm arc with R10. Then a short line from it.

Last add a 5mm circle to 75 mm line.

Now just click on the lines to sweep it to make a paperclip.
