Laser cut boxes to tidy kitchen bench

A quick project, most of it done the night before a party.

My wife complained about the mess on the kitchen bench. Lots of little bits of “stuff”, of many sizes. I thought about making a partitioned tray, but decided we might do better with an array of small boxes, allowing flexibility to use the space efficiently, and to swap boxes around if one section outgrew its container. Also, as anyone who’s had to get pointy things (e.g. drawing pins) out of a fixed compartment will attest, it’s much easier to lift up a box and empty it out.

We weren’t too sure what would be a good base size for the boxes, so I ran off a few samples of different sizes. We tried a 40mm x 40mm, and 50mm x 50mm, but quickly found that 60mm x 60mm worked well. We settled on 30mm high. Since these were just test boxes, I didn’t bother flattening the top edge, as that was the slowest step. These are all made from (cheap) 3mm mdf.

All of these boxes were designed with the wonderful (free) “Tabbed Box Maker” extension for the (free) Inkscape program. http://www.inkscapeforum.com/viewtopic.php?t=18315

The interface is very simple – just put in your dimensions and instantly get all the tabs worked out. It’s *much* slower doing it by hand, as all the tabs have to be a bit wider than the slots, to account for the laser’s kerf (cutting width).

The laser cuts quickly, but do enough cuts and it adds up. For 5 of the 60×60 boxes and 5 of the 120×60 boxes, the cutting took 17 minutes. I really need to realign the laser as I’m sure I should be getting better speeds. Here are the 50 pieces required.

And here is the remainder after I cut them out. This is a 600×400 piece of mdf, worth about $1. Alert viewers may notice a problem with the shapes. I carefully flattened one edge of each side, so the the top of the box would be flat, not crenelated. However, in a moment of dumb, I flattened one edge of the base (far left) as well. Had to recut those.

Here are a few of the boxes. Default settings in tabbed box maker gave me parts that fitted together easily but tightly, and could be squeezed into firm position. They held together quite well, but I added a bit of PVA wood glue just for certainty.

The result looked very promising. I burned a second set of 5 x 60×60 and 5 x 120×60, and one long 300×60 for scissors and a letter opener. Much tidier.

I wanted to store pens and markers as well so I made a double height box (60x60x60) and some dividers.

When you get the measurements and calculations right, laser cut parts just slide together in a very nice way.

Here’s the final (so far) result. It does spread things out more than the original piles, but at least you can find things. When we decide it’s finished growing, I’ll make a laser cut tray that just fits around the whole set.
