This one is inspired by Bukvawood.
You can cut out the nib holder from a tin jar and make a flange with pliers. Tin strip is designed to be 12mm wide and should be glued in the body (see the picture).
Fusion 360 file is attached, any enhancements are welcome!
I'll also be very thankful if you share your makes with us.
