Cactus Pencil cup holder (really a cup now)

thingiverse

I liked the original design but before printing it realized that it had manifold and other issues that would make it not slice properly. When sliced (and if you printed the original one) the top would seal up, so not so much a cup as a cactus with the top lobbed off. I first imported the file in Microsoft 3D Builder to repair it but it would still slice with the closed. So then I imported it into Fusion 360 and with a series of extrudes *cuts, joins and more cuts) and a little filleting was able to get the file to slice correctly. The original designer must have very long pencils and pens. The ones I have barely stick out the top. He did show the original dimensions in cm and this one has the same dimension. The interior height of the cup is about 135mm (about 5.25") and with one of the branches stands around 140mm. The interior diameter of the cup is 43mm (about 1.7 inches). This must be printed with supports for the arms of the cactus. Thank you to the original poster of who's work I remixed. It looks like it might have been a school project and he designed it, rendered it but never actually printed it to see the design errors. It is very aesthetically a nice design.
