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…
[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…
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…
[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…
[sc:picstyle ] This is a custom modular Beyblade launcher-compatible spinning top, designed by Jacob (7). He says, “It’s awesome!” [sc:pics folder=”things/Beyblade” l=”beyblade.JPG” r=”m-heart_bey_blade_display_large.jpg”] Instructions Use a 3M metric machine screw with washer through this, and then through one of the…
When I wired up my Reprap and started printing, I noticed that all my prints were mirrored along the Y axis — I’d set it up with the end stop at the front and configured it so that the print…
A couple of people have noticed this, so I thought I’d write it up. There’s nothing wrong — it’s just something to be aware of if you’re soldering up a Sanguinololu 1.3a PCB. If you look closely at the circuit…
Yeah, free. If you’re starting a 3D printer project (such as RepRap) at your public K-12 school in the United States for the benefit of the students, then we’ll give you a free Sanguinololu v1.3a PCB to help you out…
I’ve set out to build a Prusa Mendel for $300. So far I think I’m doing pretty well. The top part is what I’ve already picked up, and the bottom part is what I have yet to purchase — that’s…
It’s not easy to find concrete examples of shipping costs for McMaster-Carr online, and they don’t tell you what an order is going to cost to ship until after it’s already shipped — and that can be a little scary…
