Thank you for your reply!

Dear 4pwalker
Expression of "Case of PLA" explains the conditions for calculating rough printing total time only.
In actual printing, printing conditions are changed for every parts.
I can not record actual printing time of every part.
In my case, the PLA filament roll (1 kg) of the following color are used.
Transparent, white, black, silver, red, green, yellow, and dark blue
For Neutral colors I am painting.
Thank you for the comment.

In your description you said the project required a "Case" of PLA? Is that made up of 1 roll of each of the 4 colors used?

Thank you for being interested in my work.

  • Bearings
    I bought these bearing from Amazon web Shop and other machine parts shop in Japan.
    But I prepared "Dummy Bearings (STL files)" instead of metal ball bearings.
    I think these "Dummy Bearings" can be used to rotate the rotor by finger.
  • Screws
    I Bought these screws at neighboring DIY shop.
    Please contact to DIY shop person, they give you how to get these.
    There are many head type screws, any one can be used for this purpose.
    Any slight longer screws also can be used.

    I hope your success.

how can i buy the Screws and the Bearings . can i buy them online and when yes where?
