Work-Alike-Handle

This Kassel Hand model adds a handle to the top shell of Work-Alike. Work-Alike-Handle is the modified version that our team members and study participants without limb loss or limb difference on their right side used to perform experimental tasks referred to on our Experiments webpage. It’s important to note that the handle’s design was suitable for our study and we are sharing our handled version here to give ideas about how one can modify the top shell.

New To Printing? Here Are Some Helpful Tips

An .STL file contains information about all the shapes that make up the item you want to 3D print, but it doesn’t tell a machine how to make it. Let’s use a recipe in a cookbook as an analogy. You can think of an .STL file as a picture of a finished dish in in a cookbook, your 3D printer as a chef, and GCode as a recipe. When you have a picture of how a dish should look, you don’t necessarily have all the information you need to make it—you need a recipe. When you process an .STL file with a slicer software, the software takes that picture and writes a “recipe” for the 3D printer to follow: a GCode file, written in the programming language that gives your printer step-by-step instructions to create a model. Because different 3D printers need different base settings written into their GCode, you will need to use a slicer set up to work with your specific 3D printer. Your slicer will have various settings you can change to make small adjustments in how your 3D printer will create each model. Settings that work for one printer or filament may not work for another, so you might need to experiment with your setup a bit when creating your own models. We hope you’ll have fun joining in on the creation process!

Assembling Work-Alike-Handle

Getting started assembling Work-Alike-Handle? For this assembly, follow all of the instructions indicated for Work-Alike. There are no major differences in post-processing other than filing the handle and support wings of Work-Alike-Handle’s top shell. For tips on achieving your desired finish on the handle, check out the short video below. If you choose to add stick-on weights to the inside of the wrist casing after assembly is complete, you’ll need 11 oz to give Work-Alike-Handle approximately the same weight as the original iron Kassel Hand.
