3D Printable Folding Iron Sights V1.1

I made this so it would only require a rubber band to function, since a rubber band is a more common item than an actual spring.
Both the Front and the Rear sight is adjustable.

It is inspired by Magpuls new iron sights, and the locking mechanism was inspired by my Airsoft PTS sight.

---UPDATES---

• V1.1
  Thanks to Viktor Jensen, aka "No_Aim". For the idea about adding a hole for a spring in the sights!

• V1.0
  Found some really bad design choices on the rubber band holder. They where making printing the folding parts unnecessary difficult to print. (Removing the old files since there is nothing better about them)

• V0.9.6
  Rotating and re-scaling stl files, and removing non-threaded parts.

• V0.9.5
  Uploaded a stronger rear sight.

• V0.9: I added physical treads to the parts that needed it. But I will be keeping the old files on as well, for those who want to add treads by hand.
  I also made some changes to the Lock file. I made the text extrude inwards, since it would need some unnecessary rafts.
  I have also added a simple bolt and nut for mounting the sight to the weapon.
  Updated the base so it would be a slightly stronger, and had the hole for the nut raised a little.

If someone prints a set, I would love to see some images :-) I can't wait to get my own printer home!
