About this model

Finally getting around to uploading my first thing! This is an age of empires inspired guard tower (based on the keep actually, but thats not as catchy a name) designed originally for use in an aquarium hence the large open windows and doors. The design is split into four sections for easy printing requiring very few supports and the sections all have locating pins so they snap together really nicely afterwards. If you're printing this for an aquarium I would suggest gluing the sections together otherwise they have a tendency to float apart until they're fully waterlogged (you may need to weigh it down to begin with). I would suggest adding a few walls but using very low infill to save filament, I think I used 10% for most of it.
