This design was a great, but wanted to use less filament and save on print time as i planned to use Polymaker Luminous Rainbow PLA that needed to be printed at 60mm/s,

So I slimmed down most of the walls in the original fusion file, which broke some things and i had to recreate a lot of the features.

My print profile combines adaptive layer height and I added a height range modifier to reduce the infill down to 2% for 82% of the models height (10mm to 150mm, out of 170mm total height) and 20% adaptive cubic for the rest to ensure the top layers don't pillow.

All in all, this uses 282g vs 478g and i feel like you could definitely reduce it more by adding some weighty items mid print as there are a few hollow out areas without any infill.

I mucked around with the fusion file that the original author uploaded so i will upload mine as well but i kinda have broken a few things in the process so you might be better off checking out the original file on his profile.
