Bamboo box with sliding lid with blind miter hidden box joints

[WillAdams]

Worked up a technique for having a BlockSCAD/OpenSCAD file where one specifies dimensions and lid type (hinged, sliding, sawn) to get a file which is ready to import into a CAM program to make Toolpaths to cut on a CNC:

Requires a V endmill narrower than half the stock thickness and the parts are quite clean coming off the machine if one uses a downcut endmill:

and it fit together well enough for photos to be taken before it was glued up:

If anyone wants to cut one, let me know:

- box dimensions (height, width, depth)
- lid type (sawn, hinged, sliding)
- stock thickness

and I'll gladly work up files and post a link to an SVG which can be imported into your CAD/CAM program of choice along w/ some notes on how to make the Toolpaths.

That is cool!

I like it!
Where does the V-bit come in?

I'll have to dream up a reason to need a box... please hold

Mitered corner joints, after all the end mill work is done.

Correct.

Once the square endmill cuts are done, the V endmill makes a final pass along the ends of the boards to cut the miter.

Worked up a version w/ a hinged lid:

More pics please.

It's much the same as the one w/ the sliding lid, just needs a fixture to drill the holes for the hinge:

I've decided that I'll want to use a roundover endmill to relieve the lid:

Again, if anyone wants to make one on their machine, just let me know box dimensions, lid type, and stock thickness and I'll work up a file, either one in Carbide Create (free CAD/CAM tool), or as a DXF/SVG which you can import into the CAM tool of your choice (at least one person on the Carbide 3D forums used Vectric Vcarve).
