Since you pobably won't find the exactly same "pointer" as I used, I made the hole for it a bit bigger (1.4 mm) and it can be furthermore easily edited in files "vnitr rameno vedl" and "vnitr vlozka" (EDIT: there is now a special file for use of a piece of 1.75 fillament as a pointer).
The scaling up ratios can be found on one of the photos.
EDIT: Now also supports Sharpies! - use file rameno_vedl_Sharpie
