The are a lot of pen/pencil holders on here. This is a sample of a project I'm working on. A little X and Y criss cross action. Hope you enjoy!
There are only 2 files, called Criss and Cross. You will need 7 of each one.
2 perimeters, 10% infill and no top or bottom layers. Print Quality: .20 mm Speed to save one filament and time. You can choose what infill you like though!
