This holder will make it easy to strap your wine glass into most chairs armrest.

In addition to the 3d printed parts, you will need

1) A 12" adjustable strap. I got this pack:

2) 1/2"OD x 3/8" ID x 1/16" Wall O-rings. I got this kit:

3) M3 screws

PS: Part 1 will need support material, it's not fun to remove but also not too hard. I felt that I may find a better way to accomplish the integration between the strap and the part, but the current one is working well.

Pigeon is a simple cloud home surveillance camera project that uses the new Raspberry Pi Zero W single board computer ($10). It uses a custom designed 3D printed enclosure that fits the board and the camera. A wall mount is also included.

The goal of this project is to provide an easy way to setup a basic (yet functional) cloud camera at a very low cost (~$20 total). The software includes features like motion detection and Dropbox integration.

Requirements

• A Rasberry Pi Zero W running Raspbian and connected to the internet. The regular (no-wifi) Raspberry PI Zero also works, but will require a usb wifi doongle that will stay out of the designed enclosure: Buy a Raspberry PI Zero W
• A Raspberry Pi camera with cable: Buy it
• (optional) A long micro-usb power cable: Buy it
• M1.7x6mm Thread Self Tapping Screws for the case lid
• Head Combo Machine Screw with Nut, 6-32-Inch x 1-Inch for the adjustable support
• M3*6 screws for the adjustable support link with the wall mount.

Assembling is pretty straight forward, please use the comments if you have any questions. I apologize for the confusing screw/bolt selections for this project.

This spinner uses a 608 bearing in the middle, and 1/2" steel ball as weights.

Steal-Balls I've used can be found here

I recommend VXB for bearings.

You can use your preferred cap for the bearings, there are so many versions out there.
