I saw DaveMakesStuff design his boxes and just loves the shape and fins so though i would just attempt a very similar design myself to see if the method I found would work!
I am planning on making more designs with different shapes as its such a cool idea.
I am working on other projects and designs so will release those when they are ready but since working out how to o these expect a few more with a slightly refines shape.
I am slowly sorting out my desk so expect more BackToSchool designs !!
