There are several action camera quick release clips on thingiverse, but often loose or fragile. I decided design my own made from two parts. Upper part (where is the screw) is printed in other direction, so whole assembly is much stronger. Just slide both parts together with some superglue.
I recommend 100% infill on upper part, lower part can be around 30%.
If you need screw on other side, just mirror upper part in slicer.

There are two version of upper part, version 2 has greater tolerances, use it if you have problems slide two parts together or fit to camera housing.

I use it to mount GitUP Git2 camera to helmet, should work for other GoPro compatible cameras.

Edit 9.8.2016 - minor modifications on upper part
Edit 26.9.2016 - added second version of upper part

I wanted a bit more accurate mouth piece so designed this referring to pictures.

這隻犀牛是一個禮物。
犀牛是我3年前所設計的紙模型作品，我老婆一直都很喜歡這個造型，於是我花了幾天修改了紙模型的結構，尺寸剛好能放在手掌之中，並且列印出來送給她。看她收到這個禮物時的臉上的笑容，也讓我感到心滿意足。我與大家分享這個stl，希望你能在享受列印的樂趣之後，也把它送給你最心愛的人。

The rhino is a gift. It was designed as a paper model 3 years ago. My wife was fond of it so much. As a result, I spent few days modifying its construction, making it in palm size, and printed it out for her. She was smiling with surprised and pleased when receiving it which made me feel perfectly satisfied. Thus, I decided to share this stl, and I wish it could be sent as a present for the one you love.

This is a handle / blade holder for matte style blades, turning them into less dangerous and mostly useful 3D printer build platform scrapers.

I have a bunch of replacement blades for my razor (what I've called an X-Acto knife up until now :), and I had begun using one as a "scraper" for getting things off the build platform of my Ultimaker. Like Suavepotato mentioned in his description of "Razor Blade Holder and Scraper", "I do not like using a naked blade." (http://www.thingiverse.com/thing:3090)

Update: I've added a "guard" perimeter around the blade as nostarman suggested, and made the base of the handle rounded and IMO more aesthetically pleasing.

Included with the Flashforge Creator Pro is "Plate_levelling.x3g" - I didn't like that this script doesn't actually position the extruder nozzle over the bed adjusters, and of course you can't edit it as its x3g. I run off an SD card, so using something like RepG/S3D etc to assist in the level was not for me.

I wrote this script as I wanted more control over the bed level cycle.

Both the x3g and the source g-code file are included. If you want to customize the leveling positions, just edit them in the g-code, and compile into x3g with ReplicatorG.

Note
1.This cycle is setup for touching off the nozzle on a standard .100mm thick piece of paper. If you use this with the included blue Flashforge sheet (.200mm thick) it will be wrong!
2.The attached calibration cube is just here because Thingiverse won't let me just upload code.

This is a mechanical watch with tourbillon driven by a 3d-printed mainspring. The watch has a Swiss lever escapement. The mainspring inside the going barrel keeps the watch running for approximately 30-45 Minutes. Accuracy is roughly one Second deviation within one Minute (depending on print-settings).

The project demonstrates that the 3D-printing technology is developing. Compared with earlier generations of 3d-printers, the process works more reliable and more accurately. However it's still a very advanced project, because printing inaccuracies need to be trimmed manually with some watchmaker skills, or the watch won't tick.

The watch is designed with Autodesk Fusion 360, and printed with Ultimaker 2.

Many thanks to Nicholas Manousos for his great article in HODINKEE explaining the importance of my project from a watchmakers perspective. His first 3d-printed Tourbillon 1000% was also a source of inspiration for my work.

Our dapper geometric snowman is ready for the season, and he won't even melt when spring rolls around. Make all the pieces, and assemble: sticks for arms and a carrot for the nose. Place hat on head. MakerBot is not responsible for any subsequent magic.

The piece of cheese can be used as a key chain, or just to keep around. It is designed and modeled in inventor and produced using the makerbot. I decided to use yellow as my color of choice, in order for the cheese's slice to have the same characteristics as real cheese. This way the cheese slice will look real! I was inspired by my cousin to make this cheese because it is her favorite food. Even though it will be a gift, I was contemplating on keeping it for myself. I thought that it was silly to make a plastic cheese, but it turned out to be a big hit.
