I recently bought a new Jabra In-ear headset. These are charged in a small-ish case, and although nice, the product team can’t possibly have tested their final product.
Its smooth exterior makes it neigh impossible to open… there simply is no grip!? The only way is to put unnecessary force on the lid, which I fear will break the case sooner than later (oh… maybe it IS intentional… 😉 ).
So I made my smallest 3D print yet; 2 tiny (0.7l x 0.2w x 0.4h cm) dots (and one for backup), and glued them close to each side of the case lid.
Voila, a super-easy and nice solution 🙂
