This was designed by students in my STEM middle school class. ALL tips go towards the student end of the year party or to purchase more filament for our 3D printing in class. Thanks in advance!

Silk filament was used- Silk Rainbow Multicolor PLA 3D Printer Filament 3mm(2.85mm) 1KG Multi Color Printing Material Gradually Changing Color PLA Rainbow Multicolor Multicolored Metallic Color Gradient Filament CC3D

Our school logo is on one of the files, I also included a version without the logo.

Thank you for supporting the next generation of STEM students! =)
