A. Something Amazing/beautiful
Here is a 2-color model of the Statue of Liberty: a long standing symbol of American ideals. This was probably made on a printer with dual extruders.
B. Something funny or strange
Here is a 3d printed model of the Hepatitis D virus ribosome. The attention to detail is amazing!
C. Something Useless
Here is a set of printable party glasses. They might look cool but are incredibly useless. I have found party glasses after parties and have been given sets by promoters at bars and after the night is over, all the glasses do is collect dust. Despite its uselessness, there is no harm in creating party glasses. Plus, the design looks very simple and easy to make. Not much time was wasted in designing these.
D. Something Useful
Here is a printable trouser clamp for bike riders. As a student with a bicycle in a cold-weather university, I find this very useful. Whenever you ride a bike with pants on, the slack in your right leg can catch the chain and rip. This prevents that from happening by holding your pant leg against your leg in the area by the bike's front derailleur.
F. The best printable raspberry pi case you can find
Here is the best Rasberry Pi Case I found. It is functional, customizable, and mountable. Mounted to it's equipment, it is all the protection the Rasberry Pi needs.\

The project I am going to work on is machining the hop tips for the extruders but I would like to delve deeper into this idea: variable geometry hot tips. I am not sure how these would be implemented into the current software used for 3d printing but I think this idea could be very beneficial to 3D printing. The current 3D printers use 1 hot tip per extruder. The hot tip is one diameter and only round. What if there was a way to control the geometry of the hot tip as it printed? I could see this being useful for 2 different things: better plastic bonding and quicker printing. Imagine if there was a way to implement the tip diameter as a variable during printing. If a printer was printing a cube, it would use the largest diameter hole possible for printing the body and the smallest possible hole diameter for printing the edges. This would cut down printing time drastically. Also imagine if there was a different geometry that would allow a better plastic bond. I am unsure of the research that has already gone into this, but imagine the possibilities.
The 3D hubs website looks like a fantastic idea for buyers of 3D printed parts and for people who own 3D printers as a hobby. When 3D printing just started taking off, a few companies emerged who would sell 3D printed parts. You had to send your drawing files to them and they would send you back a printed part. This was amazing at the time but it was cost-intensive and took awhile to get what you wanted. 3dhubs.com is designed to eliminate the middle man. It shows everyone with 3d printing capabilities by area so that you can reach out to the closest person and get the part you want for a cheaper price. This is good because the buyers don't have to pay as much and will spend less time waiting for their part but it is also good for people with 3D printers who want to make a little extra money.
