LT.DAN Legless Sunglass Converter

Convert your working or broken glasses to legless glasses so they don’t sink when you go in the drink. If you don’t like them slap your stems back on and keep on walkin'

Holes are sized to fit 550 paracord, not the most stylish or comfortable but the most widely available.

The mounts are not universal and each pair of glasses will have different attachment methods. These designs are for glasses I have on hand.

The goal of this is to reduce waste and prevent any glasses from going into a landfill until they are completely destroyed.

Print Settings:

-----------------------

Assembly:

All of the Leg Stubs that I have designed will use the original screws from your glasses, so don't lose those. This also makes things easier when you want to switch back to your legs you'll know exactly where the screws are. 

Mounting Leg Stubs

1. Mount the Leg Stubs to your frames, 
   1. (most of these are not symmetrical so figure out which is the left and which is the right) 
2. Cut your Paracord and lightly melt the tip, then pinch and pull it so you have a tiny tip. 
3. Push the tiny tip cord through the large hole of the Cord Lock.
   1. This might be difficult keep on twisting the cord while you push to make it stiffer and eventually it will go through.
4. Now run the cord through the hole in your leg stub 
5. Finally push the tiny tip through the small hole of the Cord Lock.
6. Once the tiny tip is through cut it off and remelt the end but let it turn in a bigger blob.  Use your fingers to shape it kind of round
7. Once cooled pull the paracord and it will pull the Fat tip into the Cord Lock hiding it and locking into position. 
   1. If your Fat Tip is too Fat, cut it again and re-try. It should be completely hidden inside of the large end of the Cord Lock. 
8. Now Repeat for other side. 

Attaching Cord Locks in Back

Originally I used double fisherman knots to tie the ends and allow for you to readjust the tension on the fly. But I then realized my Cord Locks can serve the exact same purpose making it look much cleaner. 

1. Put two Cord Locks together and have the small ends facing each other. 
   1. Bonus points if you have the text on both in the proper position.
2. Now run one cord through both top holes and the other cord through both bottom holes
3. Repeat the Fat end melting step from above and your done. 

STL Files for Leg Mounts

I have a bag of broken glasses so these are all the different styles I had on hand. 

You can also design your own relatively easy, I used a 4mm hole for the paracord to run through on the mounts.

Brand Name Glasses

I modeled these to fit these exact pairs, some of these are slanted where they meet the frame body so that was fun to get right. 

• Pit Viper - Exciter
• Pit Viper - Double Wide
  • These do not use a screw they use a pin that is possibly riveted push up from the bottom and with enough force it will pop out and can be re-used. My glasses saw a ton of salt water and I was only able to get one side out plus the lenses are destroyed so I don't feel like getting the other pin out. 
• Knock Around - Ace on Base
• Knock Around - Fort Knocks
  • Both of these Knock arounds are from 2013, so I am not sure if they have changed since then. 
• Ray Ban - Wayfarer
  • These were stomped on and my mounts are very bent, your mileage may vary
• Sun Cloud - Apell?

Sunglasses Have broken Mounts? 

Drill a hole through them with a bit that is around 4mm. Run the paracord through that hole and either tie a knot or make really big melted fat end to hold in place. Then just use 2 Cord locks in the back as usual .
