About

New design added due to popular request! Please check out the project updates.

We now have a version that is optimised for soda cans and fits in the fridge! Use the link at the top of this page to see the project updates or click here.

A FIFO what now?

How long do you spend looking for that last tin of beans? Then only to find that it went out of date 6 weeks ago?

That used to be me. Never knowing what the back of the kitchen cupboard held until, one day, I made a simple cardboard FIFO (First In, First Out) can rotator.

The idea is simple. New cans go in the top and roll down to the bottom. Always take the can from the bottom of the rack and you will always be using the oldest stock first instead of pushing it to the back of the cupboard whenever you do the shopping.

The cardboard can rotator lasted for about a month and I was sad to see it finally collapse into a pile of deformed, torn cardboard. My wife, Kadriye decided that a better, more durable version was needed and I set to work designing a can rotator that could be made from MDF and glued together.

After many hours using CAD software and lots of prototypes, I came up with a nice, strong, reliable can rotator that fitted inside a kitchen cupboard and held up to 8 standard size cans. An added bonus was that you can take a quick look at the rotator and see exactly how many cans you have and what you need to buy when you go shopping.

I had 20 of the rotators laser cut from MDF wood, glued them together and gave them to friends and family to test. They all loved them and have provided some very valuable feedback on how to improve the design.

What's this Kickstarter for?

This Kickstarter is so that we can purchase a small desktop CNC machine to prototype and build a better, stronger,easier to put together can rotator which will then go on sale and help start a small, independent UK manufacturer, Karma Trading Co.

Small run prototypes are expensive and it's very hard to find a machine shop that is willing to experiment. By purchasing our own CNC machine we will be able to produce unlimited prototypes and revisions "in house", produce small runs of the designs and develop new products.

Why a new version?

The original version was laser cut which has its drawbacks and limits the type of cuts that can be made. It also had several small problems, so with the help of our 20 testers, we have started to design version 2 with several improvements:

1.   The new design will be cnc cut and easier to assemble from flat pack. The panels are marked and can only be inserted into their correct space making construction a simple 5 minute job.

2. It's more space efficient with a lower height whilst storing the same 8 cans without affecting performance.

3. One of the requests we had was to make them stackable. The new version will incorporate an interlocking stacking feature to make sure they stack easily and are stable.

4. The first version tends to move a little when new cans are rolled in so we will be adding some non-slip feet.

5. After a few months of use, the front can stop started to either break in half or come away from the rotator altogether. We will be making this stronger so that it won't happen with the new version.

6. Smooth sides, top and back will make for easy painting, vinyl covering or any other finish you like. We prefer to leave ours naked!

Why is it Open Source?

Open source isn't just for software and we are keen to help the open source hardware movement develop and grow. Once we have a good, working design then we will be releasing the full CAD files to the public domain under the GNU GPL.

We would love to see our design used, modified and made better by anyone who wants to try.

Still need convincing?

Still not sure if this Kickstarter is your thing? Take a look at the rewards and see if there is anything you like. Don't want a can rotator? Why not show your support and invite a bit of good karma with a special keyring made from CNC cut 6mm marine plywood.

Kicking it forward

We love the Kickstarter model of funding and get excited when we see others ideas grow into fully funded projects. Thats why we have joined http://kickingitforward.org and will be putting 5% of the finished product profits back into other Kickstarter projects once it goes on sale to the general public, every year for the life of the product.

Finally 

By funding this project, you will be giving us the tools we need to be able to design and build more products and you will be helping a fledgling business grow. Plus, you will be helping to support other Kickstarter projects in the future through http://kickingitforward.org.

Thank you for your support.

Risks and challenges

I personally have many years experience in delivering projects (marketing, business development, construction & I.T.) and understand the unique journey that each project undertakes. We have a clear roadmap of development for this project and I can't foresee any operational problems.

We have the design in progress and everything looks good so far. There is still some design work to do and things to work out but having made version 1 and gathered lots of feedback over the past year, I am confident that we will be able to overcome any surprise design issues.

We will be relying on the availability of materials locally and have 3 separate independant wood yards within a few miles so we should have a good supply of high quality, FSC approved materials to choose from.
