Acrylic enclosure for Arduino I've been browsing Aliexpress and eBay for decent Arduino enclusures, but I've found out they are even pricier then boards themselves. 

Then I've realized that there are multiple firms that offer cheap laser cutting - I can buy 1 sq.m acrylic sheet and order cutting multiple parts of boxes at once.

Obviously I am not the first one who came up with this idea. Has anyone seen downloadable vector layouts I can use as something to start from? Thanks.
Making your own is quite possible, especially if you own a router (or even better a router table). You need a V shaped 90 degree router bit, a tube of proper perspex glue and some acrylic sheet. The glue is hard to find, but plastic sign manufacturers generally will sell it. Unless you are a DIY expert, I suggest the gap filling type of glue rather than the watery product that only fills perfectly matched surfaces. Try searching Youtube on "acrylic box making". There are several videos. My first two efforts were pretty bad, but the last couple are fine, and are of course exactly the right size.
