I'm glad to here that.
By the way, the symbols you used for the TL071 are not in the standard LTSpice library so others might not be able to see them. Fortunately it's possible to use one of the standard op-amp symbols in the LTSpice library and embed the model directly in the .asc file.
Use the symbol named opamp2 in the schematic, right click on it and set its value to TL071.
Open up TL071.sub (normally saved in LTspiceXVII\lib\sub) in a text editor. I use LTSpice's built-in text editor.
Select the whole file and copy it to the clipboard.
In the schematic, insert a SPICE directive, by clicking on the .op button, on the far right hand side of the tool bar.
Paste the file into the text box.
Click OK.
Place the text in a convenient part of the schematic, away from any symbols.
Now you can be sure you can post it on the Internet and others will still be able to read it.
Attached is the 555 timer version of the schematic you posted but with the TL072 model I have on my computer.
