Cufflink Customizer - No support, No Glue, No hassle

A cufflink thing, that can be customised with the wording (or initials) of your choice.
Update
Added an option straight for end of cufflink .
NB: At the moment lowercase letters with a tail (gjpqy) do not work. All other letters and all UPPERCASE letters work.

Design Notes
I am not a fan of support material or glueing. I wanted a part to just print. If letters are printed on the base/bottom they can be squashed on printing the first layer. If printing from letters upwards the backing of the letters has to be bridged (or some support material used). If letters are printed on the top the cufflink end has little surface area of the print bed. Also to print a backing to the letters support material is needed).
Sideways
The letters are "sideways" as (I think) they print best that way. You get the nice effect of the lines of the z-axis but little other artefacts. With the other end of the cufflink giving lots of surface area on the print bed, ideal for a small object.
Support
The model is designed so that no support material is needed. The letters are extruded to give support at 45 degrees only where needed. The letters still look nicely embossed.
Print settings
I print with a 0.8mm brim (twice nozzle size) and a layer height of 0.15 mm
