Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am prototyping the shape for this large night light project. Let’s get Started!
I made a lot of progress this week. We ordered a roll of white PLA plastic for this project, and since it worked out well with a free shipping deal, we also got an ABS spool for when I print up another Pi case sometime in the future when I have a setup that can safely handle the toxic fumes.
While the spools were shipping, I got into Blender, and fiddled around with merging two half-cylinders on top of a box. The shape is supposed to look kind of like a house with four windows. Modeling that up took the majority of my time, but that was review. Good thing I remembered enough to recognize or look up the names and shortcuts for each tool I used.
I printed up my first prototype, and it turned out about exactly as I imagined it, only the color was solid white instead of clearish white like the demo filament that came with the printer in the first place. I modeled up an interior, and it turned out exactly how I imagined the first one. When I saw the printer wasn’t doing it correctly, I applied my mirror modifier and tried connecting the inside layer and outside layer, but the same problem must have happened again, because when I opened up the slicer with the allegedly third design, it was the second, sealed design. Good to note it doesn’t just draw the outer most layer.
While the third one was printing, I decided to slip in a few “spare parts” that were otherwise rattling around in my laptop before replacing the power port. I paused the print and noted how I would need access to the back of the printer when I install the electronics for the final light. Another minor mystery I’ve been dealing with was specks of other colors showing up in prints. While shopping for the filament, we actually spotted a spool for cleaning the printer. I don’t know how it works, but I could see the demand for such a product if someone wants to make sure if there isn’t contamination between colors or types of plastic.
I’ve used what I’ve learned to refine my understanding of this project:
Prototype shape
Hollow Prototype (present)
Model up relief pictures on “windows”
Deduce Final size
Electronics to fit final size
Refine model to hold electronics
Final product
In the interest of keeping specks of black or red out of my final print, I think I want to make a print to demonstrate the full print range of the printer. I’m thinking of doing a simple cube with just the edges. It will produce a lot of infill, but I think it will be neat to just have a cube around.
Final Question: What fun shapes would you like to see available for print for tiny computers?
