This is a 10ft wide lobby sign I fabricated for TechShop. I CNC routed the large letters out of 2” pink foam and laser cut the smaller letters out of .25” MDF.
In order to mount the letters onto the non-uniform wall I first taped a 1:1 print out of the sign to the wall. This allowed me to find the best mounting spots and make custom sized standoffs. The standoffs were made with sharp pins so the foam letters could be adjusted and potentially later replaced. The smaller letters were adhered with heavy duty double stick tape.
