Kitchen Waste RackBlind

in Homeware Design held by Jon McNerney
Contest Ended, Winner(s) have been selected.
Purpose is to make this an injection molded plastic item. Looking to get some CAD designs that include the core structures, which are: (a) precise top loop [that holds a slightly stretched plastic garbage bag], loop cutout is preferred, but optional if necessary. Loop Circumference: 28.5 inches. Can be irregular shape.; (b) bottom holder to support bag contents and hold roll of bags with some dispensing assistance to keep roll in center; and (c) a vertical component to maintain the precise distance from top and bottom components. Height 15.25 Inches; (d) two side hooks that hold a shopping bag in lieu of fitted bag.
- The top and bottom can have individual mounting via 3-4 mm screws.
- The unit would be best as a 2-3 piece construction for smaller shipping /retail box.
- item must support appx 15 lbs distributed through top ring and bottom support.
- reference for info and watch installation video for product views.
- My sketches of a potential design are attached: "Sketch_1" and "Sketch_2". This is provided as an example only.
- current, actual retail product designs attached: 2 wire plans and 1 retail package artwork. Other current product images and drawings are attached.
Note: our company is interested in selling garbage bags that fit the rack. This is the critical mission. The shopping bag hooks are a minor feature that we include for a minority of our users.
Design must be for injection molded plastic item. Most likely Polystyrene, a strong, durable plastic.
Un-assembled parts should fit into retail box with a cubic space appx 207mmx302mmx180mm.
Don't Wants:
a wire or wire type design.

Hey CH, any chance of extending the deadline. I'm working on my design but I don't think my work will get finished by the deadline. If it's possible for you then I would like to request for a deadline extension. Thanks.

3D Printer Design
We are an early stage 3D printing startup looking for a concept to use in our pitch deck. There will likely be continued work opportunities with the winner. ------------------------------------------------------------------------------------------ Style: Sleek and minimalistic. No screen, just a power button. You can go for an ultra-modern design (apple) or a retro-futuristic 50's design (Jetson's TV show). Use the color scheme in the attached company logo. ------------------------------------------------------------------------------------------ Dimensions: **Print area must be 300mm wide by 200mm deep by 200 mm tall. **There needs to be an extra .02 cubic meters of room for electronics and other components either beneath the print area or behind it. -------------------------------------------------------------------------------------------- Other: **The front, right, and left sides should be all or mostly gray acrylic glass. Everything else should be solid. (leave the top 70mm solid to hide the extruder and motors) **Modeling motors and extruder is not necessary! **The print bed must move up and down so it needs one screw and two guiding rods behind it. (see attached picture) **Include the company logo somewhere on the printer.
Mompreneur needs 3D Drawings to rid the world of boring highchairs!
Our mission is to rid the world of boring highchairs & messy cleanups, one meal at a time! I need 3D drawings of two different styles of placemats that will custom fit the world’s most popular high chair – the IKEA Antilop high chair. They’ll be made from silicone FDA approved food-grade silicone. The drawings will assist with create product moulds in China. See attached file for dimensions - although I'd prefer to work with someone who has this exact high chair in their home (as it's difficult to communicate dimensions of edges and corners). Would also like to letterpress logo into design (see attached for example).
a new pizza slicer
we have designed a new pizza slicer. we have a basic design attached below. we require a simple basic picture of the product which we can use for further market research.
New Pizza Slicer
we have created a new pizza slicer. This is a base wood board like a bread board with aa attached wire frame slicer which will cut the pizza into 8 slices like a cheese slicer. I attach a drawing of the product and require a realistic picture of the product which we can use to do some further market research to receive comments on the product and registration for future information on the product when launched. This is a very small project which should require no more that 2 hours drawing. Hopefully there will be further projects as the product is fianlised and produced.
