The Pen Holders with the Mixing Tank (Blender) model or with the Hopper model displayed, are ideal corporate gifts for clients that work in Indutrial environments. For easy printing and assembly, the model has been broken down into slip on components. This also allows for usage of varies colours from a printer that can only print one colour at a time. Attached are photos of my 3D prints produced on the Creality Pro 10S, using PLA without finishing products. The autocad dwg formats are attached, for those wanting to customize. The name band sleeve I use for my clients slips into position, so can be excluded from your assembly. A sleeve with your logo could be printed and slipped on instead, without having to modify the rest of the model.
