I wanted a custom strike plate for an outside door that I have that was marking up the door frame because of how it was installed. It had to be longer than standard with a custom spacer. I did find some strike plates already on Thingiverse, but was having trouble making the modifications to them that I wanted and coming up with a good result, so I decided to just make my own parametric version where I could easily tweak the dimensions.
I have included two STL files. One should be standard dimensions, the other was the one I made for my own unique circumstance, so it is probably useless to anyone else. It is mainly included as an example of some things you can do by changing parameters.
I have also included the F3D file. If you want to make your own customized plate, you will need to download Fusion 360 (Free for personal use) and adjust the parameters in the F3D file and then export your own STL.
Short instructions if you are unfamiliar with Fusion 360:
* Open "Strike Plate.F3D" in Fusion 360
* Click "Modify" (Top button bar)
* Click "Change Parameters" (near the bottom of the menu)
* Adjust any of those numbers, click OK, and see the result.
When you're happy with your result, right-click the top line in the browser to the left (It will probably just say "(Unsaved)") and "Save as STL", then click OK.
