This whole project uses 1.5 sq ft of 1/4" white acrylic and was cut on an Epilog Legend 36EXT.
The square and Portal cutouts were done in the normal way. Blasting with the laser until it was cut through. For the designs on the tops of the pieces, I did a light vector cut and peeled away the positive, leaving the safety film as a stencil.
Big, big thanks to Zeptozephyr at deviantART
for making the vector files I used.
