Biofeedback Butterfly Beats With A Pulse

Rearranged the collection into alphabetical/chronological order while sorting in the latest arrivals. I have a new storage/display solution in the works, which is good because at 103 cars, I have officially outgrown this cubby in this IKEA-hacked bookcase by one car. I got them all to fit because one row is now all Saabs, which are narrow enough that I could fit in 11 cars instead of 10! #WeirdCarMastodon #164scale #3dPrinted

🤡 Ah, the Ploopy Bean: because what every computer truly needs is a 3D-printed, open-source pointing stick that screams "I'm unique and also slightly impractical." 🎉 With all the allure of a glorified toothpick and the precision of a drunken octopus, you'll wonder how you ever lived without it! 🙃

S-92A Helibus 1:400 - SLA 2

The S-92A Helibus features a sleek, modern fuselage with smooth contours designed for stability and efficiency in flight. Its spacious cabin and large windows give it a distinctive profile often associated with VIP transport and advanced rescue operations. The twin-engine layout and high tail boom create a balanced, purposeful silhouette recognizable from almost any angle. S-92A Helibus 1S-92A Helibus 1/400, this helicopter is printed with a resin printer, and here is a video link about how this helicopter is printed: https://youtu.be/kDWcNtzA1u8 Here’s what each label means: - FDM: Printed on an FDM machine. These versions have lower detail, no panel lines, no engine blades, and use thicker walls. - SLA 1: Printed on an SLA machine. These include antennas, include engine blades, have thinner walls, but still do not have panel lines. - SLA 2: Same as SLA 1, but with added panel lines for higher surface detail.

Cults 3D
For todays #FreeCADFriday and my #mayke I've made a little #bike accessory. I often end up lashing things on top of my rear rack (waterproofs mostly!) and they often obscure my light that used to live on my seatpost. I've whipped up a little #freecad doohickey and #3dprinted it in PETG. It can be loosened and rotated to the side or underneath depending on what I'm carrying. Pleased with it! #biketooter I shall publish the files somewhere soon!
