3D Technology challenges you to design a Donkey Calf Raise Attachment for a Smith machine.
The specifications, requirements and technical details will be updated by January 27 based on your questions and feedback. This gives enough time for everyone to ask questions, talk with 3D Technology, and make sure GrabCADrs know what to work on and what 3D Technology expects of the winning entries.
You must include:
- STEP of IGES file.
- 3D and 2D CAD file.
- Brief design notes explaining the rationale behind the design.
- Description of design materials and dimensions.
- FEA stress results to verify design can handle up to 1500 pounds of compressive force (updated on Feb 3).
- The basic model should be light in weight but strong enough to support up to 1,500 pounds.
- The design should have a locking mechanism or quick release clamp that will allow the device to lock onto a smith machine Olympic barbell (25mm to 28mm).
- The locking mechanism or quick release clamp should have rubber padding that fits around a Smith Machine Olympic Barbell handle so as not to damage the barbell.
- The locking mechanism or quick release clamp apparatus should be able to withstand 1,500 pounds.
- The locking mechanism or quick release clamp should be able to attach and unlock from the smith machine barbell in a quick manner without any tools.
- The lower back padding should be designed to fit comfortably on the lower back even if an excessive amount of weight is used.
- The new design should be modern, ergonomic, durable, appealing to the eye, comfortable.
Additional requirements (added Feb 3)
- Material can be anything that the designer sees fit to use.
- Some form of padding should be used on the attachment clamp so as not to damage the barbell.
- Design dimensions will be left up to the designer.
- Max manufacturing cost: $300
