Printed It: Custom Enclosure Generator

Posted on by

You’ve written your firmware code, etched your own PCB, and now it’s time to put that awesome new project of yours into an enclosure. Unfortunately, all you have is a generic Radio Shack project box that you picked up when they were clearing out their inventory. If you put your project in that, it’ll have all the style and grace of a kid wearing hand-me-down clothes. Your project deserves a tailor-made enclosure, but the prices and lead time on custom plastic enclosures are prohibitive for one-off projects.

In Ye Olde Olden Days, the next step might have been to start …read more

Two-Piece Boxes Thanks to Laser-Cut Flex Hinges

Posted on by

It sounds like a challenge from a [Martin Gardner] math puzzle from the Scientific American of days gone by: is it possible to build a three-dimensional wooden box with only two surfaces? It turns out it is, if you bend the rules and bend the wood to make living hinge boxes with a laser cutter.

[Martin Raynsford] clearly wasn’t setting out to probe the limits of topology with these boxes, but they’re a pretty neat trick nonetheless. The key to these boxes is the narrow to non-existent kerf left by a laser cutter that makes interference fits with wood a …read more

Endstops That Stay Out of the Way

Posted on by

In the course of building a new delta printer, [thehans] decided he needed his own endstop design that used minimal hardware. Endstops are just switches that get hit when the printer moves at the extreme of an axis, but [thehans] wanted something with a bit of refinement for his BigDelta 3D Printer build.

The result is a small unit that cradles a microswitch and needs only a single zip tie that mounts flush, resulting in a super tidy looking piece. In addition, it mounts on the delta’s v-slot rails such that the mount does not take up any of the …read more
