3Doodler 2.0 Adapter for using 1.75mm filament

My sister has two 3Doodler pens, and I honestly found it quite annoying and expensive that they could only use 2.85mm filament sticks, so I decided to have fun making a cap that will make 1.75mm filament work on the pen.

For now I only have made a version for the 3Doodler 2.0, might make one for the 3Doodler Create too.

Not that I use 3D pens anyways, I find it easier to use CAD software and a 3D printer, but it was a fun project XD
