Warning! Work in progress!!
The lance from Fate Grand Order's Lancer Arturia/Artoria/Altria (ew).
I think I have exhausted the options in Fusion 360 to
...さらに表示 create a "complicated" pattern on a cone base shape. It is designed to be printed with a transparent material like natural PLA and illuminated from the inside with an LED strip.
The lance itself (100 cm tall!) is split into five parts that fit my printer (maximum height of 240mm), but the full sized lance is available as well. The lance parts simply slide into eachother and should be glued with an epoxy adhesive for maximum strength. The inside can be reinforced with the three inner rings. These rings are specifically designed for one of the lance parts. The rings have an inner diameter of 24mm (perfect size for a broom handle) and have a channel running through them to allow for an LED strip to be integrated into the prop, which is the idea behind this lance.
Future updates will include a proper handle design.
