I needed a nice looking marker holder for my whiteboard, so i made this one for three markers.I printed it in Colorfabb XT with 0.8mm E3D nozzle, sliced with Cura at 0.85mm shell thickness and 0.4mm layers on my UM2 with "The Olsson Block" fitted.You can download the original files in many different formats here: http://a360.co/18yuYs7
