Lexus commissioned a fully functional electric car built from laser cut cardboard. It comprises 1700 individual pieces and took 3 months, I imagine the builders were quite card-bored by the end of assembly.
Instructables user JackCarter made this awesome lasercut tank model from MDF. The functional tracks looks great and the laser is perfect for making a repetitive object like that, although they do also provide the files to make a static track if you don't have enough patience for assembly. There are lots of tank models out there but, because this comes with instructions, it is definitely a challenger for the best.
Another post from the laser cutting group now, Jocelyn has shared these Christmas letters and is currently working to complete the set. I hadn't realised how early people start working towards Christmas craft faires until I started reading these groups but I guess it makes sense. I'll keep you posted as to when the rest of the set it released assuming they letter do it amidst all the requests.
Daisymoon designs have created these spooky Shelfies to aid your Halloween decorating. They kids would have great fun decorating them and setting them up to peer over the edge of your shelves. I prefer the use of super natural poplar over mdf because it accepts colour so easily, just don't make too many boo boos while painting them.
