RotRing pen body end cap. Should do as a replacement when the original rolls under the piano and you cant be bothered shifting it to get the thing back.
You may need to experiment a bit with the thread in FreeCad and in your printer settings to get it to match the "real" thread on the body, which appears to be M10 * .75
I produced this mainly to learn a bit more about FreeCad, so I was pleasantly surprised that it actually fits my RotRing Isograph.
Note: This is not an exact copy as the original is no doubt heavily protected by copyright.
All sizes except the thread are subtly different (and even the thread is probably wrong), and my design use is restricted to "non commercial".
I though it best to keep it that way, just in case a certain large German Stationery company were thinking of sending the goons in ill fitting suits round to have a legal chat.
