This is just wall lettering in Comic Sans MS with a 5 inch height. They are just under ½" thick. Some modifications were needed to make them, mostly just adding a bunch of fillets. I have been printing them at 25% infill and they are pretty robust. I used a 3 mm radii if you are wondering if you can CNC these. I purchased double sided tape to install these on the wall.
The author marked this model as their own original creation.
