This is a tiny hollowed-out cap in the shape and size of the iconic TO-92 transistor. I made it to conceal a SOT-23 or SOT-23-6 SMD package on a 3.5×3.6mm flex PCB. Originally the goal was to make something that looked as much as possible like an authentic black-epoxy-resin TO-92, but I was inspired by lee cyborg's amazing alligator clips to try something more colorful!
As you can tell, these prints are tiny. The walls are only 0.45mm thick! I printed these on a Formlabs Form3B in Clear v4 and then dyed them with Jacquard Piñata inks in 95% ethyl alcohol.
Yeggi search engine results for 3d printable Pusheen stuff. I was specifically searching for keycaps.
This is a reimplementation in KiCad of Don Froula's (http://projectmf.org/) PIC-based bluebox. The circuit was by Don Froula and the board layout was by Phil Lapsley (http://explodingthephone.com). It is so named because of Don's production of a close replica to the bluebox pictured in the October 1971 Esquire article "Secrets of the Little Blue Box." This version is based upon the ATtiny85 microcontroller.
There are three branches in this repository. Branch 'v1' is as close a duplicate of the original board as I can manage. As is, this board forms its own lid for the Radio Shack 230-1801 enclosure. The 'v2' branch is modified such that it can fit in the bottom of the Radio Shack enclosure. That one is probably a better choice for replicating Don's replica. The master branch has been modified to fit a Hammond 1591XXM dimensions 3.3" x 2.2" or 85mm x 56mm) enclosure, which I feel is of much better quality and utility.
This board requires six volts DC. Two or four CR2032 coin cells can be mounted in onboard holders or six volts applied to an external power header. Keystone 103 holds one cell each. Keystone 1026 and MPD BH800S hold two cells each stacked. I chose to try the MPD BH800S because I was uncertain if the Keystone 1026 would fit within the confines of the case.

Greyprints for fabbing a box to hold your TL866 programmer kit.
LYNX's goal is to create a customizable computer control system that accommodates the individual needs of each user. The project stands on two pillars: open source, which provides all necessary files and instruction for self assembly, and the shop, where the tool can simply be purchased.

Want to build a RasPi cluster shaped like an old-school Cray supercomputer? 'course you do! You can find the greyprints and see how to assemble it here.
Somebody posted greyprints for making replacement parts for the Nintendo Power Glove.
Somebody modelled greyprints for a RasPi 4 case that looks like a miniature BeBox. A circuit board for implementing the blinkylights on the front can be purchased from OSHpark.
A collection of greyprints for Construx parts.
Greyprints for 3d printing a modular hard drive rack. Modular. Mount a bunch of standard PC hard drives vertically. Bolt some fans onto the side to blow air across them and keep 'em cool. Seems like this would be an ideal setup to use with some hot-swappable drive connectors.
Downloaded to Windbringer. Fab, rivet into Leandra's chassis to replace the awkward steel drive backet that requires pulling out all the cards.
