Matt, can you spare 5 mins to review my box design?

[Paul Beard]

Hi Matt/anyone else who can spare 5 mins and knows something about these things,

Attached is my box design for my 4x4x4 led cube. Can you have a quick look to see if you can see any obvious errors please. I hope to have this ready for the laser cutter on Tuesday (fingers crossed we can get it going for vector files).

The prespex I have is 2mm thick as far as I can accurately measure.

I realise the "lid" is not perfectly square, Apparently I did not make the pcb square, as I had intended, its 2mm wider in one direction!

The pcb will form the floor of the box, but raised up to allow room for a battery box in the base underneith. The pcb has 4 m3 screw holes in the corners, and the 4 small shapes you see in the attachment are brackets that will (I hope) fit into the walls and the pcb will be screwed into them. I'm not sure what diameter I should make the holes in those brackets. The m3 screws should bite firmly into them without risking a fracture of the bracket.

Thanks!

Hey Paul,

Looks good to me. I'd probably suggest making the holes a different colour and get it to cut those first (just incase pieces drop as they are cut, it makes sure your holes stay in the correct place).

I've been in for some more training and managed to sort out accessing the laser cutter and getting it all to work so we should be good to go :)

Thanks again for the assistance Matt.

Here is the box temporarily assembled:

I have not attempted to clean up the scorching yet. I may have to re-design those brackets. I made them with 3 sizes of holes, but none were in the correct place! Also the shape of the brackets makes it hard to get the cube inside the box....

Looking good as a first attempt. A bit of tweaking and it'll be spot on. 

Glad we were able to get it done though.
