The images above is the final product after designing and printing the guitar Keychain.
Step 1: Design Your Object in Fusion 360
I used the program Fusion 360 to design a guitar keychain. To be able to make the figure of the guitar I used several circles and an elipse. Then I trimmed the extra lines and mirrored one side of the guitar to the other part.
Step 2: Mirroring
After I mirrored the other half of the guitar I draw the handle and made the circle of the middle.
Step 3: Extrude
Then I extruded the parts and used the fillet option for the back part of the handle.
Step 4: Convert the Fine Into a .stl File
Right click in the name of the Fusion 360 file in the Browser options and select the option Save as STL file.
Step 5: Printing
At last I printed the part in 3D.
Step 6: STL FILE
I provided the STL file above.
