#cad and 3d modeling

I think it’s quite amazing how my quality of life has instantly improved TENFOLD now that i don’t have to come up with words anymore and can finally sing again while I’m working.

Music really is something else…

a fun pro tip is that if an online storefront has a "3D preview" of an object you can probably grab it as a glb file and throw it into blender with perfect scaling, full textures, and detailed dimensions that you can then pull off for other projects (or, like, I've seen people straight up dump Ikea furniture into blender scenes for animations)

I want to add some printed parts to this keyboard and here's a perfect to-scale model I can reference and use to do boolean operations with to make my parts fit, even on complex curves

Hey you fucks, it's time to learn CAD. This is your sign, there will be no right time. Open a cad program and start making. Do it now. Then send me ur models and I'll print them and put them on my fridge like the crayon drawings of our youth.

Fusion and OnShape have free versions, if you're a college student you may be able to get the most common CAD programs free while you're in school, either way, get to work.

Im looking to do some free custom 3D modeling. Shoot me a message if you're interested!

I got bored and just... made a 3D model of an office chair (the cube is 1x1x1m). If anyone has tips on how to make a cusion for the seat and the back, let me know.

Want to build your own Piano Coat Rack?

I put together some plans for the Piano Coat Rack so that if anyone else wants to try to make one they have a starting point. I ended up putting them on itch.io for free since tumblr doesn't really like PDFs or zip files. The plans are free for non-commercial use. I also have a section describing some of the process to hopefully make it fairly easy to replicate.

I put these plans together in FreeCad, so along with a PDF version of the technical drawings there are also full 3D models that you can use to get a better understanding of how it goes together. If you notice any oddities or mistakes or have any question please just me up!

Also if you make one please tag me, I would love to see it!

My 3D-printer is driving me nuts right now. It's a constant spaghetti festival whenever I try to print one specific thing. A thing that was printing perfectly fine yesterday but today it just won't. Everything else works just this one model...

These photos are from the air flow simulation I did yesterday, to find out what impact the wind would have on the structure of the identification buoy. I recorded the animations to make it easier to analyze.

It was fun to do this, I discovered that I can make several different types of fluids, which could be useful in future projects. The article is almost ready, along with the boat and buoy codes.

Here are the charts with results generated from Solidworks:

Generally I don't do this, but I'll put the translation of the analysis I put in the article here, maybe it can help someone.

Although it is not common to carry out engineering tests in this specific context, we chose to conduct an analysis dedicated to aerodynamic conditions, aiming to understand the effect of wind on the structural integrity of the buoy. To carry out this study, we used Solidworks, making use of the fluid simulation system incorporated into the program.

Initially, we modeled the buoy structure, assigning specific materials to each component. Subsequently, we establish the necessary boundary conditions to faithfully simulate the behavior of the structure in real conditions. In the next step, we created surfaces that represent the wind pressure in the region where it impacts the buoy, and defined the area in which the wind pressure would be applied. The application of wind loads and adjustment of analysis settings were carried out using the “Flow Simulation” tool.

This process allowed an accurate representation of the aerodynamic conditions on the buoy structure. Additionally, we adjust relevant parameters for the analysis, ensuring a comprehensive approach.

The simulation execution culminated in the generation of a comprehensive report, documenting the results obtained. The interpretation of these results provided valuable insights into the structure's performance under simulated aerodynamic conditions. This engineering test highlighted the importance of considering aerodynamic conditions when assessing structural integrity.

It is possible to highlight some fundamental reasons for the importance of this analysis, such as the assessment of structural integrity, assessment of operational safety, design optimization, which can result in savings in materials and manufacturing costs.

The Montagem_boia.SLDSAM model was configured with standard parameters, carrying out 57 iterations to achieve convergent results. The mesh was defined with basic dimensions (Nx = 40, Ny = 9, Nz = 17), and boundary conditions were established to represent the fluid environment of interest.

The physical time interval considered was 0 seconds, and the CPU time required for the simulation was also recorded. The simulation results revealed an interesting distribution of fluid properties and flow characteristics. The total number of cells in the mesh was 7626, all occupied by the fluid. Among these, 1106 cells were in direct contact with solids.

The mesh dimensions (X,Y,Z) indicated a significant extension of the model, with minimum and maximum variations in each direction. Analysis of the velocity field revealed a range of [0 m/s; 7,510 m/s], indicating different flow regimes within the simulation domain. The pressure varied between [101294.37 Pa; 101430.23 Pa], with a reference pressure of 101325.00 Pa. The temperature remained relatively constant, with values ​​varying from [293.20 K; 293.21 K]. The fluid density showed a minimum variation, within the range of [1.20 kg/m^3; 1.21 kg/m^3].

There was no consideration of factors such as heat in solids, radiation, porous media and gravity to simplify the model to meet the specific objectives of this simulation. Based on the analysis of the images obtained, the reduction in wind speed becomes visible when facing the structure of the identifying buoy.

Notably, the average wind speed in São Paulo, situated at 25km/h, is insufficient to cause damage to the aforementioned structure or to displace it from its original position. It is also worth noting that, when encountering the obstacle represented by the buoy, the wind flow tends to bypass the structure mostly from above, to the detriment of the sides.

This observation suggests an effective resistance of the buoy to direct wind impact, contributing to its stability and structural robustness. The results clearly indicate that the structure's resistance to wind action is remarkable, since the force exerted by the wind did not reach levels that would compromise the integrity or stability of the configuration.

The solidity of the structure in the face of these conditions suggests that the design presents a robust and adequate response to the expected wind loads.
