I was looking around on the internets for some cool plywood projects to do. I found a link to add a macro to Inkscape to draw living hinges in your projects. Along with the files for that, they had this free pencil box plan, so I downloaded it, and gave it a try. The living hinges are very cool. I resized the plan because when I opened it up it was gigantic…but in re sizing it I made it slightly too large…when you put a pen inside of it it disappears! But this was just to try out cutting a living hinge. I used the standard 3mm plywood cutting operation, but I slow the speed down to 180mm/min and I did three passes because I was having problems getting my ply to cut all the way through with consistency. The first pic is a little out of focus…sorry for that!
Living hinges are very cool, and I have found a bunch of plans I want to purchase that incorporate them, as well as design my own pieces using them.
