Great job Moke.... what are the dimensions (printer capacity)?
Do they work similar to 'tainers? Can you open a box half way down and tilt the top forward?
I've always found that the item I wanted was always on the bottom and if stored in cabinet it was a PITA to get to... that's why I initially hated 'tainers till I discovered these bases... You could use the same concept with 3D printed/wooden mobile bases.
If your first cut is too short... Take the second cut from the longer end... LBD
