I made a lower-profile version of the 3D-printed case back in January and realized I forgot to post this here. This should be retrofittable onto existing 3D-printed Bostons (though you will need some new screws)
This reduces front height by ~2mm, reduces the width by ~2mm, switches to flat countersunk screws so that the screw heads no longer protrudes on the top of the keyboard, changes the side profile a bit so that the top and bottom bezels are more even, and optionally revises the right key separator a bit near the arrow keys so that the bezel transitions better into the right case half.




Files and a draft conversion guide for existing 3D-printed Bostons are on Github here:
