A remix, of a remix, of a remix. Chopped this up in 5 minutes on tinkercad. The first model I tried printing was, frustratingly, about 1mm too large for my printer... and sadly, the custom version of cura that it requires you to use only allows you to rotate objects 15 degrees at a time. To fix both issues at once, I made this ultra minimalist version. Hopefully it will get the job done.
