FreeCAD rounded, somewhat parametric wedges

A collection of all purpose wedges. These aren’t done with OpenSCAD but with FreeCAD, but are rounded (filleted).
There are four versions of FreeCAD files

• A wedge with a sharp edge, to be printed lying flat
• A blunt wedge, to be printed lying flat
• A wedge with a sharp edge, to be printed upright
• A blunt wedge, to be printed upright

There are a few ready made STL files:

• One to prop open a window (Fensterkeil.stl)
• Two versions to prop open a patio door (that has quite a bit of ground clearance)
• Two without a specific purpose in mind

The idea is that you take the FreeCAD files and change the size to what you need. It’s a bit harder than with my dial-a-wedge, sorry. Do it like this:

• Download FreeCAD and get it running
• Load one of the fcstd FreeCAD files.
• In the tree view, double click on “Sizes”. You should see the spreadsheet
• Change the values to what you want. Make sure to keep the = and mm.
• Go back to, wlog, the upright_wedge view. Tab at the bottom.
• Check that the shown shape looks OK. There are view controls at the top
• Check that in the tree view there are no exclamation marks as warnings
• If there are problems, it’s easiest to close without saving and to try again. Change fewer values, and only by small amounts.
• If the wedge looks good, select the last item in the tree view. The wedge should turn green in the main view.
• Look for the dropdown in the tool bar and select “Mesh Design”
• You should now have a “Meshes” menu. Select “Create mesh from shape …”
• I have to select the “Standard” radio button. “Mefisto” produces empty meshes.
• Click OK
• There should be a “fillet (Meshed)” or similar item in the tree view. Select it.
• Click on the “Export a mesh to file” icon, enter a file name, select the file type (STL or OBJ) and click “OK”,
• Et voilà, you’re done. You have finished your first FreeCAD lesson and can now go ahead and slice and print your customized wedge.
