Wine Bottle Gift Boxes

-

I had a local craft fair this weekend, I wanted to add a few extra/new items to my range so that my stall would be very different from last time. I've seen lots of variations on this wine box so I thought I would make my own version. The living hinges at the top allow the sides to be pulled close and the lid closed, it also a great place to put a handle. The fretwork patterns down the sides make them unique to me as well as the custom labels attached to the side. (svg here)

I didn't sell very many and I'm not sure any were going to be used as wine bottle boxes, one lady wanted to put plants in it and another was going to put fairy lights in hers. Neither wanted the the custom labels so I'm pleased they were only held on with blue tak. It's definitely given me food for thought with the next craft faire looming.

Laser Cut Cryptex

This is my laser cut cryptex. It features 28 different characters and 9 rings, giving a total possible 10.5 Trillion different combinations. I took a bit of time developing the design so that I could add some nice features. This cryptex file is laid out so that you can have any number of rings in your own design. The best feature is that the codeword is changeable, each locking ring has an outer letter ring that can be placed in any one of the 28 different positions. Once the rings are back in place the ring locking bars can added and they prevent the rings from being modified until the box is open again. It's a bit hard to explain so I made a video showing how it all work (svg here)

It took a long time to assemble this so I lived with my initial design choices but if I were to remake it I would adjust the file to make the ring locking bars out of 6mm ply and maybe put some blind holes onto the code rings to prevent the code being brute forced.

Laser cutter speed difference

-

Here is the video of my two laser cutters cutting the same tile side by side. It prompted a few people to ask 'how come the 30W tube is much faster than the 100W tube?'

I picked the new laser cutter based upon speed. It had a few specification stats that suggested it was fast and the photos showed a fairly lightweight head etc. Now that I have the laser in my possession I can see all the design decisions that make it fast. In the case of these Carcassonne tiles I only need the full power of the laser when I'm cutting the tiles out.

The low power engraving lines are done with minimal power, only 8% of the 30W tube. The metal RF tube gives me much more control over the low end power, the head can fly around at 100mm/s, twice the speed of the larger machine. The engraving can be done at 1000mm/s, again nearly twice the speed and empirical evidence suggests that it is actually moving at that speed.

The 30W laser can easily handle the 3mm poplar ply wood at a sensible 35mm/s, t…
