Also good for composting and making room in your recycling bin
I mean, you could make a jig to use a box cutter to make consistent width strips very easily with three pieces of scrap wood. But this commenter coming in here for the express purpose of trying to shit on 3D printer hobbyists was a stupid move on his part.
I meant without printing anything, for anyone without access to a 3D printer. This was in response to the above comment about freehanding it.
To use an ordinary box cutter for this purpose all you need is something to use as an endstop and something to use as a fence, and they have to be parallel to each other.
