3D model description
This is my first Assassin’s Creed inspired hidden blade 3D model (Syndicate edition) equipped with a unique mechanism, every single detail of that is 3D printable, except for a nylon cord. There’s no need for screws, nuts, springs, magnets, ball bearings or even rubber bands. All you need is 100g of standard PETG filament and a piece of nylon cord (0.6-0.8mm thick).
[UPD Oct.03.2023: a version for PLA was added, where a 3D printed spring is replaced with a rubber band.]
An assembly approach has been inspired by the handguns assembly process, which can be done in a matter of seconds by using no tools. By combining several functions in each detail of the mechanism I managed to reduce the overall number of them down to 11.
All the parts are ready to print and placed on a bed the most optimal way, taking into account layer arrangement and seam positions.
The files have embedded supports where required, but non-presupported files are also included.
Blade tip is rounded for safety reasons.
I'm going to stylize this model for other Assassin’s Creed game series later, you can subscribe my profile in order not to miss new versions.
3D printing settings
UPD Oct.03.2023
There are 2 different versions of the mechanism.
The first one was made for PETG, it contains a 3D printed spring (the folder name is "Syndicate_Hidden_Blade_PETG").
The second version was made for PLA where a 3D printed spring was replaced with a piece of rubber band (acceptable thickness is 1.0-1.5mm), the folder name is "Syndicate_Hidden_Blade_PLA".
The main video instruction is dedicated to a PETG version, it shows all the process of 3D printing and assembly process step by step: https://youtu.be/v9SSSFaRpQI
It is also relevant to a PLA version, except for a rubber band related part, so I’ve made another video, just about this difference: https://youtu.be/mDPNlCua8GE
