Personalized Pen Holder

I made these pen holder as gift for the kindergarten of my daughter. There is two sections : Tigrou and Ourson. So I personalized the pen holders with the name of the sections. And there is two designs because after the first print, I thought the size of the pen might be bigger than usual pen in the kindergarten (pen for whiteboard for example). So the Ourson is made for 4 pens of the same size while the Tigrou is for 3 pens of different sizes. I include the FreeCAD files if you want to personalize you pen holder.
Sorry, I forgot to take some pictures before offering the pen holders.
