For the teaching prop project I chose to create a 3D version of the Barrel Model of Culture diagram. I used the image of the diagram below from Studyblue as loose reference (
Sketch used in a 360 degree revolve commando to form the barrel.
Rectangular sketch used in a 360 degree revolve command to form the base/ environment section.
Arrow sketches used in a two sided extrusion and an extruded cut to form the slots for the arrows in the model, as well as the arrows themselves. A separation of 0.25mm was implemented in the extruded cut to make a slide-fit for the arrows. Immediately after the extrusions to form the arrows and arrow slots, the barrel was split into three separate bodies to form the three different barrel sections of the barrel model.
A text sketch was created and used in a extrusion to make split faces along each of the three sections of the barrel, the newly split faces were then pushed inwards to extrude the text labels into the model.
A text sketch was created and used in an extrusion to make split faces on the front of the base, these faces were then pushed inward to indent the “Environment” label into the base.
A circular sketch with an outer separation of 0.3mm was created in between each section of the barrel model and the base, these were then used in an extruded cut upwards at each section to make a hole for a peg, then used in a normal extrusion upwards on each piece to form the connecting pegs. This is the peg forming sketch between the environment and infrastructure sections.
Peg forming sketch between the infrastructure and social structure.
Peg forming sketch between the social structure and superstructure.
Finished barrel model of culture in fusion.
Drawing showing dimensions of the finished model.
Layer height: 0.2mm
Adhesion: none, no brim used
Time for print: Approximately 17hrs 47mins
Filament usage: 203 grams
Print Mishap: The Ultimaker 3 does not print with the same tolerance as the Ultimaker2+, so two pieces printed were unusable as a result. It is best to try to keep all prints in an assembly on the same printer model due to this difference in tolerance.
