This is a Caster for Engineering
It won't work go to the folder
The first assignment is to create the caster base. The base's dimensions are 200 mm x 120 mm and 8 mm thick. It has 6 holes 10 mm wide and 20 mm from the edge equally spaced along the edges.
This was my first Onshape part and following along with Dr. Shields made it super easy. I learned about
- sketching (shortcut shift-s)
- constructions lines (shortcut Q)
- dimensions (shortcut D)
- extruding both add and remove (shortcut key E)
- linear patterns (no shortcut)
Onshape is awesome. I found it really helpful to rename all my sketches. It is going to be a GREAT year in engineering.
The second assignment was to create a caster mount. The Base's dementions were 120mm x 120mm and 8mm thick. It has 4 holes 10mm in diameter and 20mm from the two clostest edges. It has one big whole centered on the origin and 30mm in diameter
This assignment was very similar to the base I learned about:
- The use tool (shortcut U)

The third assignment was to create a fork. I created the fork within the Base and mount sketch because they went together. The fork was an 80mm (diameter) circle extruded 8mm. two addition extructions were added on each face. A 40mm x 5mm rectangle 15mm from the origin and 20mm (diameter) cylinder. Rectagle was extruded 75mm and mirrored over the front plane. An additional 15mm (diameter) circle was added inside the previous 20mm circle and the 5mm difference was extruded 60mm. Fillets and chamfers were added to make the final look more poilshed
Base, Mount and Fork in Onshape
This assignent, while more difficult than the base or mount was still very easy. I learned about:
- Mirror
- Fillet (shortcut Shift-f)
- Chamfer
Ohshape is awesome. I found it really helpful to rename all my sketches. It is going to be a GREAT year in engineering.
The fourth assignment was the tire. This was the first part I made in a different part studio because it's dementions were not built off the others in any way.
This assignment was harder than the fork but still not difficult. In this assignment I learned:
- How to make a trapezoid
- Revolve
Ohshape is awesome. I found it really helpful to rename all my sketches. It is going to be a GREAT year in engineering.
The fifth assignent was the wheel which is the support structure for the tire. It was built in the same part studio as the tire.
This assignment was the hardest of all the assginments. The dementions were weird and it took me a couple tries to figure out exactly what to do but it was still alright. In this assignment I learned:
- Construction Lines (L + Q)
Ohshape is awesome. I found it really helpful to rename all my sketches. It is going to be a GREAT year in engineering.
The axel and collar were made as a seperate parts in a document, the bearings were made as a part of the tire and wheel, and the Washer was it's own part
Axel and Collar Tire and Wheel Washer
These three parts were not so difficult as the wheel. In this assignment I learned:
- Symmetric Extrude
Ohshape is awesome. I found it really helpful to rename all my sketches. It is going to be a GREAT year in engineering.
I assembled all the part studios into Sub-Assemblies. This included the three different part studios
This assignment introduced Mates which required a very long assignment to complete. Luckily mates are fairly easy in onshape even easier than other CAD programs. In this assignment I learned:
- Fasten Mate (M)
- Revolute Mate (also M)
Ohshape is awesome. I found it really helpful to rename all my sketches. It is going to be a GREAT year in engineering.
I made a new document and brought all the assembled parts into it. Using fix and revolute mates I asslembled all the parts into the final caster.
This was the final assignment in the caster assembly it wasn't very hard and I finished it pretty quickly
