Stip Center tool Remix

Update 23-03-2024:

Added a new type of holder (rev 2) with the same working as the rest of the design. It allows for min 6 mm and max. 16 mm stip pencils. It allows you to use any diameter in this range. It can also be screwed on the tripod with the same screws and in the same holes.

-------------------
I was asked to print a bunch of the original design, however I had a hard time finding the right screws and also could not find a suitable spring for the stip pencil/brush holder.
The O-ring version of the holder worked fine in my opinion but my SO thought otherwise.
So I redesigned most of it, biggest changes:
-New holder uses a M4x25 bolt and M4 nut, can be screwed down with a 3x12 screw.
-Tripod is slightly adjusted at the bottom to create some clearance for the cross
-Studs now include the pins, it is one part now.
-Cross was redesigned to allow studs to slide in from the outside.
-Cross can be "closed" by putting in the distance piece between the two holes at the end
