Incredibly simple small cylindrical storage for desktop or wherever, using scrap wood - some leftover 3/4" pine in this case - and any size of PVC pipe, depending on what you want to use it for.
CAPTION: I made the shortest one and largest one for this contest. The short one goes in my toolbox to keep little bottles from bouncing around and disappearing, the tallest will hold wrenches on my work table.
Workholding is achieved with tape. Since this is such a simple shape, it's trivial to mark the workpiece bottom with a ruler to ensure you don't cut into the tape and gum up your endmills..
CAPTION: note the markings. I use Nitto tape, which is great stuff.
I sized the caps, in the C2D file below, for 3" PVC. I tried to leave a bit of room for glue. I use hot glue, which works great on PVC for non-pressure related applications. I cleaned the PVC with a little acetone to make it look nicer. I probably won't ever bother to paint it, but it is definitely paintable, and can create a nice, finished look, see below.
Note that PVC varies pretty widely in thickness, depending on what's happened to it during its time on earth. If you want the caps to fit tightly, you'll want to measure and adjust my file to your own purposes.
CAPTION: this is so loose it falls right off. Since I'm planning to glue it, that doesn't matter.
CAPTION: same cap as above, but in this pipe it's a tight enough fit that I have to push it very hard to persuade it to go in.
It's possible to take this idea REALLY far, as I did with this next one, which I made shortly after I got my Nomad. It's definitely overkill, and kinda pointless, but I had fun doing it, and learned a lot of basics from it:
Here it is unloaded:
CAPTION: as you can see I tried to make each hole shaped exactly for its intended object. Worth trying if you're new to CNC, if only to realize not to bother with such silliness (learning what NOT to do is a big part of any new skillset).
CAPTION: I suppose if you wanted to, you could make an enclosed, canister style storage.
Feeds and Speeds are all in this Carbide Create doc. Cutting out two of these from 3/4" pine took 19 minutes on my Nomad, using a straight bit from C3D.
