3D printing 6. Final Project: Water Bottle Floral Vase

For the final project of the 3d printing class, I created a floral vase that can be used anywhere with a regular plastic water bottle. Basically you just cover your water bottle with this vase, and you will put flowers inside the water bottle filled with water. Now the regular water bottle has transformed into a modern and simple vase.

I carefully measured the water bottle so that the vase fits the bottle, and then designed a simple unit cell that can make a patterned texture to cover the whole surface of the vase base.

Experimenting with making inverse (negative) patterns. This shape above on the left is the unit cell.  Draw lines, Extrude curves, Cap, Make cube, Boolean difference or split... to make the inverse pattern!

It took so much time to boolean difference 10 x 7 array of the pattern compared to one unit cell.

I had to cut the edges so that when both edges meet they create a smooth pattern.   FlowAlongSrf on the vase base with the use of the reference plane on the pattern. Now I erased the vase base. The design is ready!  I had to have many different testings because my obj files were having a weird problem all the time whenever I exported.

This is how the design is supposed to look like.

When I tried to import obj files to Cura, it didn't work at all because the files were corrupted making lines and holes instead of solids. So I had to revisit Rhino and check if any part on the process I made a mistake. I started from the scratch like 10 times, and tried to export partially but with different number of array of the patterns. For some reason, it only worked normally until 4x3. However, whenever I warped the texture onto a surface of something like vase base or just simple cylinder, it broke again. The errors in the files were like this: all the points of the object are pointing to the center of the grid, which completely breaks the shape of the object. How they are breaking down looks kind of cool but it was really stressful because I couldn't find any reason those are doing it and I had to create the same project again and again...

Artistic Chaos.............. why always making lines to the center?

This was the maximum amount I could export normally in .obj so I printed bunch of it to test the texture.

Finally, Jesse in my class told me that I should try using .stl instead of .obj. Boom! It worked. so the problem was the .obj format itself. I still don't know why it's doing it.. So yay for the vasejesse.stl! Now, 8 hours and 30 minutes of meditation to go.

3D printing 5. Final project progress

Instead of the lighting for a cup, I decided to make a vase that covers a water bottle.

I drew bunch of guidelines for the water bottle to make sure the shape of the vase does not intrude the bottle. Then I put the profile picture of the water bottle to make sure the lines are almost accurate.

I drew a curve along the edge of the bottle and revolved 360 degrees. I am going to put a 3d texture that I design on top of the vase model surface! and the 3d texture mesh itself will be the vase that goes with the water bottle! 

3D printing 4. Chopstick Helper ver.2 & Final Project Idea

So my chopstick helper I made last week had a dimension problem. When I printed it out with a 3d printer, the four holes in this device came out smaller than they were supposed to be. So I had to test this out with wooden chopsticks on their narrow parts.

This time, I made the holes 1.6 mm bigger than the actual size. Also, I wanted to test out a different material with higher resolution. 

For my final project, I want to make a cup light, which is a portable light that fits into the bottom of a cup. It is meant to offer a fun experience to users who enjoy drinking in daily life or at a bar by lighting up their drinks with different animations and colors. I am going to use a neopixels LED ring and program the lighting based on the accelerometer's xyz values, which detects the movement of the cup. So if the users lift up the cup to drink, the lighting animations and colors change. In order to make this device, I need to design a holder for the LED, the accelerometer sensor and a battery, which also fits into the cups.

3D Printing 3. Chopstick Helper

For this week, I designed a "chopstick helper" to assist people who are not familiar with using chopsticks. Users have to put this device at the top of the chopsticks to fix two sticks together at a certain distance like the sketch below. I first created this device in Rhino and imported the design into Cura for 3D printing.

I used LulzBot TAZ6 this time. The print did not come out as I desired because the four holes collapsed a little. Next time, I will try printing with Ultimaker for the more accurate details because I can use 0.4 nozzel instead of 0.6 one with this printer.

3D Printing 1. 3"x3"x3" Lego head

We were asked to model something that fits inside a 3″x 3″x 3″ cube. Using Rhino as a tool for the first time, I modeled a lego head that fits the cube because lego is my lifelong favorite toy!
