Chocolate making is messy business. One of the steps in nib-to-bar chocolate making is to extract the liquor from the nibs. We use a Champion Juicer. Inevitably, when you add nibs to the chute … a lot of them fly back up the chute and land all over the kitchen. So I built this hopper …

Background I use a Handibot for CNC woodwork. If you aren’t familiar, Handibot is a portable CNC router that you place on top of your workpiece to make pre-programmed cuts. It can cut the same designs and perform most of the same tasks as a full sized CNC machine, but compared to full-size CNC machines, …

Here’s a simple vibration table for making concrete tiles, made with a Black and Decker Mouse, some screws, nuts, washers, and compression springs, and scrap wood. The springs I used are 1 3/4″, 1/2″ OD, .054WG, but any reasonable gauge should work. Tighten the screws to create a little compression. Use a pair of nuts …

Mecanum wheels are cool. Each wheel is composed of a series of rollers, pitched at 45 or -45 degrees. When moving forwards and backwards, the rollers do not engage, but when the front and back wheels rotate in opposite directions, the rollers engage to move the vehicle left or right. These wheels are 3d printed, …
I wanted to build a storage bench for this area in my attic workspace. There were a couple of challenges: This house is more than a hundred years old, and nothing is square. The window sill is +1/2″ higher left-to-right. There’s a vent in the wall on the left side. The windows are casement-style and …
Medium: Walnut. I purchased this nice free-standing wardrobe and wanted to place it in dead space in the entry hallway. Unfortunately, this placed it right on top of the cold air return vent for our furnace. I made a skirt to elevate it and match the height of the baseboards, then fabricated this vent screen, …
The Xaar 128 is a piezoelectric inkjet printhead used in large format vinyl sign-making. It *might* be useful in 3d printing, conductive ink, or masking applications. Why piezo? TLDR: Most inkjet printheads are “thermal”: They work by superheating a fraction of the ink in a chamber, turning it into gas, which expands to force the …
Macro photo printed as a large format bitmap made up of 3d boxes in PLA Plastic, printed with Makerbot Replicator 2. Size: 6.5 feet X 2 feet. Each “pixel” is a 3 dimensional box that tapers into a quadrilateral opening. The corners of the quadrilateral are determined by sampling the grayscale intensity of a grid …
Medium: PLA Plastic, printed on Makerbot Replicator 2 in 8 parts. Modeled in Rhino3d with Grasshopper. Size of the veronoi part is 20″x20″. This was a super-challenging project to do with an FDM 3d printer, due to the large number of overhangs and small cavities. Each part took 10+ hours to print, but perhaps even …
