This is a design that I put together for PonokoID ponoko.com/ponoko-id. I came up with the design based on the requirements for a Wired Magazine article. It's a fun and simple design that can be made with a few odds and ends from the local hardware store.
I really want to see someone come up with a 5UP design that looks like 5 health bars out of a computer game. Enjoy.
The design is free of charge. You can use it on the proviso that you share a small part of your personal expertise in the education of others. You can do this in any way that you wish and your contribution need only be small. If you’re a busy person then you can always contribute to a charity like The Fred Hollows Foundation http://www.hollows.org.

Toss Your Most Brilliant Product Ideas Into Ponoko.com's Fishbowl
By Sonia Zjawinski
"What We Wanted
A pencil holder that doubles as a sharpener.
What We Got
Frosted acrylic guides channel the pencils into store-bought sharpeners. A handle provides leverage, and the rear panel can be removed for cleaning out the shavings."
I've put all of the objects into the one SVG file, although you may want to cut the body and guides out of different materials, as shown in the photographs.
The box base should be cut from 6mm material. The pencil guides can be any thickness.
The original SketchUp file that I created can be downloaded from Thingiverse http://www.thingiverse.com. You can modify it and then use my "SketchUp SVG Outline Plugin" http://code.google.com/p/sketchup-svg-outline-plugin/ to create different SVG files. See my Instructables http://www.instructables.com/member/flightsofideas/ for more information.
The design fits 10x5mm (0.6x0.4in) single hole sharpeners and 6mm (1/4in) threaded rod. There are holes to allow 2M screws which give it a steampunk-ish look. You will also need a handle (you may need to change the spacing and diameter of the screw holes). A cabinet magnet can also be used to keep the rear panel firmly in place.
To assemble, glue the box together with PVA or another clear-drying glue. If using ply for the base, simply drive the screws in by hand. If using something like acrylic you will have to pre-drill and perhaps tap holes into perpendicular edges.
Use epoxy to glue the sharpeners in place. You may also want to modify the design to include a channel for shavings if the sharpening blade does not sufficiently clear the 6mm material. You can also attach the cabinet magnet (optional) at this stage to the rear panel.
Once dry, use the threaded rod to fasten the guides into place. Use nuts and washers to sandwich the guides and the top panel of the box. Add dome nuts to the tops of the threaded rods. To get the threaded rod to the length that I wanted, I simply used a Dremel to cut a single 2ft piece into 6 segments.
Attach a nice handle to the box, add pencils, and start sharpening.
