My mentor, who first got me interested in Lasers, gave me this file 2 years ago. and until today never made the larger one. Wicked kewl design no glue needed holds itself together with pins from each of the 4 sides and bottom.
I’m not sure what scares me more, The fact that my mentor knew I’d need this, or that there are still yet 2 larger sizes. (also which I haven’t YET made.)
They can be taken apart, but it takes a bit, the 4 smaller ones are 2 years old now and never had an issue with them. Including getting knocked over by the kittens.
