I have a question for you, probably quite basic but I cant easily figure it out. The thing is, I am paralyzed on my left side after a stroke. So I can not use left arm. Now imagine how it is to try and cut your nails on the right hand! Not easy.
So I want to make like a sleeve that I can push over the arm. The sleeve should have area on top where I can place my chin (ie concave) and depress the arm with my chin. Now, the measurements of the arm is 10mm at the top and 13mm at the other end. Thickness ca 1mm. The length not critical, ca 50mm.No need for the sleeve to be closed underneath (it could be difficult to print). I would prefer the sleeve to be open but grasping around the edges so I slide it on.
With the help of the sleeve I can lay the cutter flat on table and use my chin to activate it.
Appreciate if someone can look at this. Even more appreciated if you made a video so I can see how it is done.
Well, nowadays there are more advanced tools for cutting nails.
Search for “Electric Nail Trimmer” “Electric Automatic Nail Clipper”
and you will get something like this kind of things for a few tens of dollars/euros:
From the point of view of modeling the extension you are after in SketchUp, here are a few suggestions.
First, set SketchUp’s units to Meters with Display Precision set as high as it goes. Make sure Length Snapping is turned off.
If you want your extension lever to be 50mm long, you’ll model it as 50 meters long in SketchUp. This will help you avoid issues with tiny faces.
Model at least the existing lever first and make it a solid object. You can use it as a “cutter” to cut the void in your lever extension once you’ve modeled it.
I would model the extension lever in place around the clipper’s lever so you don’t have to move things around. Center the model along the red axis. The levers will be symmetrical so you could get by with modeling half and then using the Flip tool to create the other half.
After creating the slipper’s lever component, give it aa tag so you can easily show or hide it as needed.
When it comes time to export the .stl, select your extension lever component, after select Export and the file type, go into the export options. Make sure you have Export only current selection is ticked and that the stl units are set to Meters. That will ensure only your extension lever gets exported and that it shows up in the slicer at the right sise.
