Photographer Ray Dauphinais of Creative Concept Studios, just sent me those two image with the following text attached. The first uses a 2$ level to make sure that the Blaster projection is 100% leveled.
The other hack is placing the Blaster on a mini ball head rather than on a light stand. This makes shifting from horizontal to vertical projection a breeze.
So a huge hats off goes to Ray for sharing those hacks.
