Furniture scriber/transfer tool for carpenters

I saw a tool like this on ebay day before the competition started and thought I could use that stand added it to my wishlist thinking of buying it at some point and then this competition showed up and I though why not to make it myself.

I made it so it needs a m4 thumb screw threaded directly into the pencil holder or you can use alternative version where you add threaded insert for better stronger part.
