CAD DATA.
CKB_118_t2.stp ; step format file
CKB_118_t2.123dx ; Autodesk123D file

STL file.
CKB_118b.stl --> CKB_119b.stl ; frame for CardKBD
CKB_118t.stl ; key-top layer (prototype1)
CKB_118t2.stl ; key-top layer (prototype2)

Update : 1/17-2019

A slightly bigger key may be required.
It was thought that "CKB118b.stl "(frame for CardKBD) should be improved.
...Therefore, the following files were added.

CAD DATA.
CKB_119.stp ; step format file : the key-shape is slightly bigger.
CKB_119.123dx ; Autodesk123D file :The shape of the bulge that holds the board is made a little longer.

STL file.
CKB_119b.stl ; frame for CardKBD
CKB_119t.stl ; key-top layer (prototype3)

Update 3/16-2019

Box shaped shell case for M5Stack CardKB with frame and key-top.

CAD DATA.
cv031.stp (.123dx) --> cv034.stp (.123dx)

STL file.

cv_031pn.stl ; Hinge stopper data.

Update 4/18-2019

Little improvement on the shape of the case.
