Double D punching

[the publish date is retroactively published]

I have bought a load of disks for my C64C, and a lot of them said double-sided, but with only one Write Protect notch. Back in the day, there was such a tool to be able to punch another hole on the other side of the floppy disk, nowadays they don’t exist. However, someone found out that this tool, not only punched the right hole shape it’s the right size! You can buy it from Amazon here.

So, once I had this I was able to look for a 3d print for this, it was a paid-for print, hence why I am not hosting the STL here, but I will give you this link!

This is what my one looks like:

Works perfectly, and is technically a brand-new Notch tool! So with this, you can now double your floppy disk size!
