3D Printer Club: Kid-CAD Test
[sc:3dclub-intro] Today we tested some basic CAD instruction out on a fifth grader very much like the kind we hope to see in the 3D printer club that we want to start at the local school. We used TinkerCAD. The…

Mounting a PCB Heatbed (MK1) onto a Reprap 3D Printer
To install the heated print bed for my reprap, I placed the PCB on top of the plywood top print plate (which is slightly larger than the PCB), clamped it in place, and then used the holes in the PCB…
Highly Configurable Wheel (One Wheel To Rule Them All)
I built a framework for robot wheels a while back using OpenSCAD and used it to create a few different wheel styles. I recently decided to combine them all into one massively configurable wheel model, and add a number of…
3D Printed T10 Lamp Shade
Here’s a 3D printed T10 lamp shade that I designed and printed last night. A few weeks ago while searching for LEDs, I noticed an ebay listing for very inexpensive 12V automotive lamps that combine nine bright white LEDs. I…
T10 LED Lamp Shade (12V)
[sc:picstyle] UPDATE 6/20/12: Added Netfabb’ed versions. This is a press-fit lamp shade for inexpensive 12V 9-LED T10 automotive lamps. I believe these are sometimes called “wedge lights,” and are used as turn signals or interior lights. (I got mine on…
How to Make an Arc or Wedge in OpenSCAD
OpenSCAD apparently doesn’t have an easy way to make an arc or wedge, or any way to do a partial rotate_extrude. This presented a problem when I started to design my Parametric Encoder Wheel, because in order for it to…
Parametric Encoder Wheel
[sc:picstyle] This is a parametric encoder wheel that allows you to set circumference, internal width, shoulder height/width, mounting hole diameter, number of timing holes, as well as several parameters for captive nuts, alignment/snap-together pins, bolt holes, and inset of those…
New Image Plastics Measurements
I received several filament samples from New Image Plastics in Ohio, ranging in length from about 1-4 feet. Here are the measurements I took from various points on each strand. I measured all the way around the filament and recorded…
Velleman Metal Detector Enclosure
[sc:picstyle] This is a project enclosure for the Velleman Metal Detector Kit, commonly available at Radio Shack. [sc:pics folder=”things/MetalDetectorBox” l=”reprap-metal-detector-case-01.JPG” r=”reprap-metal-detector-case-02.JPG”] Instructions Clip the PCB into the bottom of the case. (You may need to bend the corners out a…
Repraps for Education Survey
We’ve released a brief, 3-minute and 7-question anonymous survey about repraps and educations with the goal of determining the level of community support there will be for a school club curriculum. The survey will be advertised available here and in…
