I just started working with Tinkercad this week, My printer should be here next week, so I am trying to get a head start with print designs by getting all the upgrades ready to go. One of the things I did was use an electronics box to house the dual mosfets and CPU. I added another designers 40mm fan covers to the box top. So my question is, when I share this design mod, what is the protocol for acknowledging the original designers? Would I need permission from them to use their designs to create another design? I looked for this in the forums, but everything is general and I couldn't find an answer there.
