Extras - Screw

 We're back with another "Extras" blog post back to back. Welcome!


Here's a screw I made in Rhino.




In class, we looked at a few machine screws and measured them with digital calipers. At the time, I didn't have access to digital calipers, so I managed to search up the dimensions of the screw online. The internet is a wonderful and vast resource of immeasurable information, thereby allowing me the secret knowledge of machine screw dimensions down to the precision of tenths of a millimeter. Exciting!


For reference, I didn't actually use this table, but this is about what it looked like when I searched it up in class.

Here is a rendered view of the screw.


A few major points of focus for this class were learning how to create the threads for the screw by using the "Spiral" and "Sweep1" commands, and the creation of the cap, using cutting objects created with Loft, and ensuring there is "depth" to the hole, as there would be for a real screw.

Here are close-ups of the threads and the cap.





I will say, I thoroughly enjoyed making this object. Creating the spiral and subsequently using Sweep1 to see the threads come into 3D was very satisfying. If given the chance, I would absolutely use this combination for other projects. It's just so simple, satisfying, and fun. 😎

Surface Design Study: Laser Cut Sample

Image
 After making a few adjustments to my 2D electrical outlet design, I was now ready to make a laser cut sample on wood. Though I've cut wood with a laser cutter before here at AUArts, this would be my first time engraving a design rather than cutting one out. I was quite excited—the smell of smoky wood and the texturing of engraving we saw in class was something I looked forward to. A few edits needed to occur to my design for it to be serviceable, however. It needed to be in greyscale,  needed to be the correct size for the laser cutter, and within the correct greyscale spectrum tailored to the laser cutter equipment. Here is the design put into monochrome (may be a bit different as I took the photo and then needed to adjust it afterward as well) It may be obvious at first glance that the background is an entirely different value—that's because it is. For my digital design, I enjoyed having a darker background to play around with, as I find values and colours more aestheticall...

Reversed Engineered Object: Selection

Image
Selecting objects to dismantle for this project was difficult, only as I didn't actually possess a lot of objects that could be dismantled 😂 Here are the three objects I chose to take apart and examine for the first part of this project. First, we have a semi-standard inhaler used to treat asthma and other respiratory disorders. The inside of this object was particularly interesting to me, as the structure of having an open hole that is tailored to allow for medicine delivery though not permitting the medicine canister to "fall through" seemed intriguing. The next is a stick of lip balm. This one seemed relatively simple to execute and also had some interesting structures like the centre piece to push up the stick of balm, and the rotating bottom. Finally, I have a pen my mom bought from Singapore. Sadly, this was on the cheaper side, so it's nothing fancy 😂 I won't lie and say that I like this design, even as cheap as the pen feels physically. The scaling textu...
