Today I am designing a cup to print to test out 3D printing! I feel like maybe I will be too into this due to making cups in glass and ceramic already. However, if it is good I can maybe use it as a mold for the future!
I drew a bunch of designs and I figure I will just play around with them until I have something that I like.
The first thing I did was make a box that was 5x5x6 so I would know my maximum height and width. Then I took out a ruler to see how big 6cm tall is. Oh my gosh! That's so small haha. I think some of my ideas are too complicated here! It's still too early to tell if that is a relief or not.
Somehow in getting my ruler from a drawer I had inadvertantly gotten rid of my top and side bars in rhino and now am stressed out. Uncool. I literally don't even have a command bar. Tried closing rhino and reopening but it's still like this. All toolbar things I'm getting when googling seem to be about getting fancy schmancy toolbars. I tried clicking "restore defaults" under settings>toolbars. wow this is so classic me that when I'm feeling confident and optimistic some dumb thing like this would happen which will probably take me hours to figure out. Love it.
Thankfully someone on the internet also had this problem and window>restore window layout did the trick.
For the first one I decided to try to make the "traditional" cup. I make two circles with the top one only being slightly larger than the bottom one, and lofted them. I then capped the object then shelled it removing the top face. Done!
I then decided to make a line and rotate it 30 degrees then mirror it, just so I had a little guideline of what would work.
I made an....ellipsoid? then rotated it horizontally at a similar angle as the cup and put it adjacent to the cop so that it overlapped at the bottom but not at the top. I then decided that I wanted 13 of them cutting out parts of the shape, so I rotated and copied it around 13 times after dividing 360 by 13.
I wanted to have a lip, but knew it couldn't come out at 90 degrees due to how printing works. I then used curve told to make a line about the same angle as the cutouts from my cup. That was not sharp enough though so I rotated it a bit then compared it to my 30 degree measure line to make site that it wasn't too sharp.
After a bit of mucking around and making a line to use to measure another circle I was able to sweep2 to get the curve to the wider part around the cup shape... but oh wait. somewhere In there I deleted something important, like a wall of this cup. Horrible. At least I kind of know how to redo it hopefully quicker.
I kept doing "undo multiple" until each time a "delete" showed up. eventually I got way back to before I had done all my boolean differences.
I am not really sure why the rendered part looks good but the wireframe perspective looks like it is missing the outside surface? I guess we will burn that bridge when we come to it. EDIT: I was just looking at it wrong.
I tried rebuilding the sweep part to make the cup larger at the top but honestly it looked a but dumb like a super mario pipe so I got rid of it.
I tried chamfering the edges over and over but it wasn't working for me, so I undid all of that. The filleting seemed better.
I decided that it wasn't interesting enough, so I would do the twist thing. I keep in every class struggling to use fibbonaci somehow because I'm crazy, and I realize now that 13 (the number of bottom booleaned out objects I have) is a fibbonaci number. What if I twisted this so it was 5 of those over one way, and 8 over of the other? I like just seeing what math things do.
Ugh trying to find the center of an object for twisting is kind of like a weird fishing minigame.
I copied over my cup a few times. I twisted it 5 notches over, or 138.46 degrees. to rotate it 8 notches over it would be 221.538 degrees. I wasnt sure if twisting it the same direction or the opposite would be better so I went for the same first since mirroring it would be easy.
It looked cool by itself being twisted the same direction but I don't think that combining them would be interesting so I mirrored the second one.
Now I am trying to boolean union them- possibly the last step in making this? However, now my computer is giving me a spinning screen of death. Nooooo! It's been a minute, so I guess I will go put some bread in the breadmaker and check on it after.
In three hours I will have fresh warm bread! Yay! However, I still have the spinning rainbow circle of waiting. Gross! Did I do the thing again where I made it too complicated and now it needs to think really hard? Hopefully I don't need to force quit rhino or something like that. I guess I will go and start getting stuff ready for the dog park, since once I am done with this that was my plan.
After about 20 minutes (I know because I checked how much time was left on the bread) it seemed to have finished but the boolean failed. I just took them apart because honestly I kind of liked how they looked separate, like using an optic mold for glass. After rewatching the part of the tutorial were the object was not happy because the lines were not precise, maybe my crazy rotating and joining won't actually work, so I'll just leave it. It's just a test anyways, and I went way too hard on my laser cut test.
