Like I said, you can buy them pre-cut for you. For instance (not saying that this is the best deal, this was one of the first ones that turned up when I searched Google): https://www.etsy.com/ca/listing/577285643/foam-modelling-bricks-small-1000 Obviously you have to pay a small premium for them, but for smaller projects it may be worth it. If you were to build something at the scale of the bridge I posted, or many multiple smaller projects, then the Proxxon (or similar) will be cheaper in the long run (plus you have full control over the size of the bricks you make and you can create many other things). Hope that helps!
