gridfinity pencil sharpener box

This is my attempt at a #gridfinity pencil sharpener that collects the shavings.
The entire thing is 1x1x6u, the shavings box being a 5u gridfinity box itself.
I used a sharpener bought from HEMA, but I am not sure if it is a "standard" one.
It's about 9.5 x 14 x 25mm.
The lid needs to be printed upside down and does require support.
You can support-block the 2 small overhangs at the top, they bridged just fine for me.
To install the sharpener, remove the blade-screw, put it in and put the screw back.
If the snap fit is too tight, sand back the locking parts a hint.
