A continuation of my lantern diffuser project, based off the same archetecture as my D4/D4S diffusers but optimized for the much more floody D18. This emphasizes top up or top down use, throws light down and around like a proper lantern, and tries to be more compact.
The Mk2 AIO version is available now, I am working on a 2-piece version that will allow the removal of the central reflector to maintain light throwing capability.
I can confirm that up to the maximum regulated output, PLA is safe temperature-wise. Use at your own risk past Hybrid mode, and Turbo would surely melt some things after a minute.
.16-.24 layer height recommended
~5-8% recommended to help build the shelfs
Print open side up, no supports needed
