Rotring Holder

This 3d model is the perfect 1 in 2 solution for your rotring pens. It can store up to 3 rotring pens and 10 graphite tip containers. With a simple but ingenious rotary mechanism it enables you to search through the different tip containers. It can surely work with other graphite pens other than the rotring brand ones because of a high tolerance. It has an easy 2 part assembly which is also es to print out. Print & assembly:Only the upper body needs supportsI included 2 lower bodies. 1 with spots for non slip pads and another one for 2mm cork sheets.You can remove the supports easily using the lower body jusk like a pepper grinder as seen in the assembly guide. The only non 3d printable parts are the non stick pads or the cork sheet.The bottom for the cork fits a cork 2mm thick and 34mm in radius.The non slip pads that i used are 10mm in diameter.I think 2 walls are enough and 3 layers on the bottom and top should do the trick.
