www.tinkercad.com It's really simple interface, use the tutorial. Watch it all the way you can manage to construct any object, engineer an idea or the other STL files and rescale them to send to your printers slicer to be 3d printed. Oh almost forgot, its free for hobbyists. ;)

If the flow rate is too far apart leaving streaks instead of sealed overlays then increase your flow rate. Go by 10 to increase until your satisfied with the flow of the filament through the nozzle head.

Sorry to inform you but with the current way the platform is headed and with interest I will be switching skool platform to 3d printing and the use of the platform tinkercad and other programs to slice and program obj STL files to your 3d printer. Thanks for the understanding. Feel free to message or ask any questions. I have a funding going on as a campaign. To raise money for medical bills as well for a family member. To contribute or for other ways to help feel free to message. Thanks and God bless you all.

What is something you want to know how to do but can't find information or ambition?
