About the last model
It is 3D data with accurate parameters by 3D CAD.
All models are formed based on uniform design criteria.
Parameters are varied according to application and design characteristics.
The same toe shape is available in different heights, allowing the user to choose the desired height.
The download package includes the left and right models for design, the left and right models for shoe production, and the parameter list.
The data in STL format can be loaded on almost all 3D printers and NEWLAST machine tools.
Models for design are available for right and left. Please use whichever you prefer.
You can use what you modeled with an FD printer as it is for pattern production.
It is quicker to ask a shoe mold maker who has NEWLAST's equipment to make a plastic last for the last model.
The last model is made by removing 0.8mm of the back part of the sole, so that the height setting will not change even if a steel plate is applied.
You can also use the shoe model as a body for modification, since the bottom surface of the shoe model is highly accurate.

Description of the last parameter
The parameter list is included as a CSV file.
The item examples and explanations in the list are as follows.
If you want to scale 3D data
The model provided is compatible with shoe sizes of 23 cm.
If you want to adjust the size before modeling with a 3D printer, you can adjust the size if you have software (mainly 3D CAD) that can import STL format data and perform 3D scaling.
The scaling factor is calculated by the following formula.
Magnification in the X-axis direction (bottom length)
Fx = 1 + length you want to extend (mm) / original bottom length (mm)
Magnification in the Y-axis and Z-axis directions
Fy = 1 + Ball size you want to increase (mm) / Original ball size (mm)
The original dimensions use the numbers in the parameter list. 
You can also rotate the model around the Yj axis before scaling, align the center of the heel curve and the tip of the toe with the X axis, and then scale to get the same result as scaling at the last factory.
About the heel model
It is 3D data with accurate parameters by 3D CAD.
It has an appropriate tilt angle that adapts to the arch of the DDL last model, and is designed with various elements of shoe making in mind.
Inkjet and stereolithography high resolution printers are required to check delicate shapes.
The thickness of the front tip of LouisType Heel is designed to be 0.3mm.
The sharp edges around Cup are chamfered by 0.1 mm to avoid chipping. 
The length and width of the bottom are matched in millimeters, making it easy to manage the top lift.
The package contains data for 5 levels with different tilt angles.
The angle between the shoe and the heel may not match due to various factors in the shoe manufacturing process, but we support up to ± 1 ° in advance. 
Heels made with a 3D printer are not suitable as parts for mass-produced shoes due to cost and strength issues.
It is intended for use as a shoe sample and as a model for mass production molds.
