I made this custom case for my 3D printed spectacles:

Custom case

It holds the glasses by the edge of the frames, so the lenses are suspended above the bottom of the case without touching anything and no padding material is necessary to prevent scratching.

And being specially sized for those glasses, the case is no larger than it needs to be.

Did I mention that I love 3D printing? 🙂

Looks great - how many versions did you make to get to this?

Thanks!

I just made one initial print but I didn't leave enough free play in the frame holder at the bottom of that case, so while it worked, it was kind of a pain to insert the frames into it. I widened the play from 0.4 to 1.5 mm and now there's zero usablility issue.

Another unexpected problem I discovered with that first print is that I couldn't tell the top shell from the bottom shell when the case was closed. I completely overlooked this and it turned out to be a massive PITA: 50% of the time, I would open the case upside down. Silly eh 🙂 It seems obvious in hindsight.

But I like the symmetry of it. So I added "engraved" text at the front edge to tell if the box is the right way up before opening, and put my name and a description of the particular correction in that case as a bonus.

The rest - stiffness, hinge, lid fit. magnet fit - came out okay the first time out. I'm getting really good at knowing the printer's tolerances in advance and leaving enough play for things that shouldn't assemble with an interference fit.
