This is my make-through for the week's assignment. Grab a cup of coffee!
Journey 2 (Design) will happen Now.
Target: Design Assembly parts.
Characters: 3d-printers- Fusion 360( student version)
Place: My Home
Describe what commercial product did you choose for the assignment and why?
Describe how did you design the enclosure? Are you designing for 3D Printing, laser Cutting, or both? Which types of joints did you design for the assembly of your enclosure? and How did you design them? How did you design the mounts for the electronic components within your enclosure?
Describe how you prepared your design for fabrication
Describe how you fabricated and assembled your enclosure model
Describe how you gave your enclosure a better finish look
Describe problems you encountered as they happened throughout the process. How did you solve them?
Make sure to Use screenshot images and videos to document the process
Step 1: Rotating, During the design, I found it is so difficult to rotate the bodies in fusion. I didn't know how can I rotates the bodies. No using of scroll.
Step 2: Assembly, No mates need for drawing Parts in fusion this is so hard to me but after using I found it is easy ways in designing. It will detailed explain in my design.
Problem: Using some features in Fusion
Potential Solution: Try and error method and some online search until I reached to my goal
Describe my product: It can't name my design as product. it can be teaching product of almost use all snip fits. This is my goal. why I choose this design? To grab to my mind all benefits that I learnt, so that small box which (it can be wrong idea but this what happen)
I design my enclosure using fusion as 3bodies (not parts solid works) Cover and body edges. I only used 3d printer.
Snip Fits used are T-slot, side slide nut pocket bolt, edge guide in cover to easy assembly with entire box.
How Design them: using the dimension of bolt and nut (width, depth ,and length). I want to disappear all bolt and nut appearance so that I left in my design the depth of bolt head. designing using the ( extrude and extrude cut, combine, subtract, and new sketch ) my box dimensions are 50mm wide, 90mm length, and 25mm height.
preparing my design for fabrication: Print setting ( it is relation between time taken with quality) so that 0.2mm normal is medium choice (time less with good quality). choose your filament type I used (Generic PLA) and don't forget to choose your 3d printer name ( Original Prusa i3 MK2S). Infill is 15% is better with less amount of filament. slice now use the name of material, color and amount of grams as name of your G-code file.
After my future of thinking I found my self will use more than 15 grams of PLA (which mean no second trial will be available), and I am worry for failure so that I decide to make some modification on my design with same snip fits.
Bodies, Converting edge body into two small bodies (left and right edge) keep the cover as is (i thought about making the cover in wood using laser but my snip fits not be the same because of the guide edge and depth of head nut).
Preparing the files with same previous step
Output printed parts.
During Assembly, I made two mistakes first mistake i didn't take enough tolerance when I design the house of nut (shown in figure) I want to make the two circle concentract when i put the nut so that I believe that when I use small tolerance it will be good. it is so small to all nut. the hole of nut is shift outside the pocket hole with nearly 1mm. I try to remove material by hand but I didn't find suitable tool in my home.
What make me happy that I learnt from all mistake and applying what I learnt in the Group project (joint of 3 faces acrylic). I hope that I have much time to repeat printing my design again Inch Allah (as soon as possible).
Left Edge
Arrow 1: show guide edge and arrow 2: show depth cut of the bolt head.
Right Edge
Assembly of my design it can be use as holder box of two battery.
What I learned this week is...
Using Fusion 360
importance of tolerance you make suitable tolerance.
Designing snip fits
Fabrication using 3d-printer.
Using PrusaSlicer
Learning from my mistakes.
