About this 3D model
This is a remix of Turtleman's low poly bear. I put some holes in its back and turned it into a desk top pen holder. The holes are 15mm. I made them large enough to fit my fountain pens. I have printed this without support but it does not look nearly as good as with support. Turtleman recommened support density of 35%. I used 10% and it worked out pretty well. Just play with it and see what works best for you.
