If you don't own a 3d printer you can have these parts printed for you using a low-cost 3d printing service such as 3DHubs.
Print settings may vary between printer and type of filament used, but in general you should be safe with the following settings:
- 20% infill / 1.5mm retraction
- 2 shells
- 80mm/s print speed
- 0.20mm layer height / 0.4mm nozzle
All of the parts have been given pseudo-anatomical names, which helps by making them easy to organize and refer to.
Below is an explanation of each printed part that goes into making a Humble Velocipede.
Much like your own shin, the shin of the Humble Velocipede forms the lower part of its leg.
The thigh forms the upper part of the leg and is the main connection point for the hip and many of the ligaments.
The ACL connects the Shin to the Thigh, and is the most visible of all the ligaments.
The PCL serves as the connection point between the shin assembly and the hip shafts.
The LCL is the longest of the ligaments. It connects the intersection of the Shin and the PCL to the crankshaft.
The MCL is the smallest ligament. It connects the top of the thigh to the crankshaft.
The endplates act like bookends which capture the hipshafts and protect the internal mechanism.
The top bar is the key to finishing any Humble Velocipede. This bar acts as a spinal column to hold the rest of skeleton perfectly rigid. This version twists 90 degrees once inserted through the plates to lock everything into place.
After printing all the parts, the Thigh, MCL, and ACL will need to be put together in preparation for assembly.
