Crystal Eyeglasses Case

Crystal Shard Glasses Case

The Idea:

I wanted to design a case for my glasses that was simple, easy and quick to print but had a unique look about it. Along with that, I love printing in vase mode! I also wanted something easy to adjust to fit multiple different types of glasses and their frames so I came up with this case. I am also a firm believer in open-source and modding something to make it unique and your own, so I have included the STEP as well as the Fusion360 files. I cannot wait to see what you come up with!

Printing:

Printing this case is fairly easy in vase mode, upright. The only few limitations are that your printer must be able to handle at least 45deg overhangs and you need a fair amount of cooling for the first 20 or so layers as they have a few sharp corners which could warp without cooling. It's also a fairly tall model so keep that in mind when choosing your material and speeds as you could get some wobble if you are printing too fast. 

I printed with a brim to just help adhesion a little. 

The two halves are designed to clip together snugly but if you are having troubles with them being too loose or too tight; increase or decrease the scale of the quicker printing, Bottom part by 0.5% and work your way up, or down. 

Keep in mind that vase mode prints aren't usually the strongest, so try use a thicker extrusion width to keep the parts strong and make sure to use a material with excellent layer adhesion such as PLA or PETG. I wouldn't recommend ABS for these parts as we all know how much ABS loves to delaminate when given half the chance. 

There are two variants included: Small & Large

These are designed for thinner frames and rounder frames, respectively. Adjust to your preference, though!

Modifying:

I encourage you to adjust and make these parts unique to you. If your glasses don't fit the cavity, scale the two parts un-uniformly but make sure they are scaled the same! If you want to check the size of the final part, just take the dimensions and minus whatever double your wall width is. For example, a part that is 150mm long will actually be 149mm if your wall width is 0.5mm because there are two walls. 

Have fun!

Tip: To more easily separate the two halves, press your thumb below the joint on the flattest face and then lever the cap off. Much easier than trying to pull them apart straight.
