Pinecil stand with metall sheet

I haven't print it yet, though I have no pictures

I didn't like the Idea of the hot soldering tip touching plastic, even PETG.
so I projected the cutout for the tip to 2D and make a slot to insert a piece of 2mm metall sheet.
mine was lasercuted from aluminium in the mechanical workshop at work but I'm sure, it should also be possible with stand drilling machine an handsaw
the metal piece is 20mm x 20mm in size, the hole has 11.5mm diameter and is 1mm off-center towards the opposite edge from the opening

the base is unchanged, I just renamed it, to better find it in my Filesystem.
the Openscad-File is mostly the one from the original thing (so it needs the BOSL-Library linked in the discription of the original thing), but I included it for the case, someone wanted to use less thick metal sheet or need wider tolerances for their printer.
Also I left the Projection Part in it, just coment the other calls of the modules out and decomment the upper projection block (the lower projection
