Pen Grip for Lamy Safari FP (Schmidt PRS)

I present my replacement pen Grip Section, for use on the Lamy Safari Fountain pen.
This part has been designed to allow the Scmidt PRS rollerball feed to be used in the Safari, without requiring any irreversable modifications.

To complete the assembly you will require:
A Lamy Safari Fountain pen,
This printed grip section,
A Schmidt PRS Rollerball feed,
A universal ink cartridge or ink conterter.

 the Schmidt PRS rollerball feed is installed by screwing it into the top of the grip section and then an ink cartridge can be fitted into the grip's base.
The Lamy Safari Fountain pen's original grip section has a black plastic ring clipped into it's base. This part needs to be removed and installed onto the replacement grip section in the same place. The Tail section of the Lamy pen can then be threaded onto the grip.

I would suggest printing this item in the Black High Definition Acrylate material, as it is the closest printable material to the pen's original, in terms of appearance and surface finish, although it should be considered less durable.

Due to the varying nature of 3D printing, I cannot guarantee that this part will definitely work with the Lamy Safari, although I've made every effort for it to do so.

I plan to make as many refill types compatible with as many host pens as possible, so If you have any suggestions on refill adapters or ansilliary parts like this one, please let me know and I can hopefully make it available, depending on the relative sizes involved. I have now created dimensioned drawings of over 80 standard and obscure ballpoint, gel and rollerball refill types, so I like to think that I have a fair idea of what is and isn't possible.
