returns the slot size value for a desired fitting during programmed design procedures

Description

It is not a perfect method. Better it would be to use frames that explain the fitting by a letter such as
'fit-c' or 'fit-cx' if several frames are used or a combination of 'c' and arbitray frame name
fittings {'c','0123'} with the number as fitting frame name
The results using a FORM2 Printer with clear Resin V4 and 50µm resolution were on Aug. 16 2020 by Tim Lueth for bore hole radius oversize (plus == increase of bore hole radius):
+0.05mm not to be pressed in at all by hand - probably destroyed by hammering
+0.10mm Difficult to push in by hand and difficult to remove even with a hammer
+0.15mm Easy to press in by hand and can only be easily removed by hand
+0.20mm easy to join by hand and falls out by itself when shaken
+0.25mm falls out by turning under its own weight
The results using a FORM3B Printer with MOdel Resin V2 and 50µm resolution were on Aug. 11 2020 by Tim Lueth for bore hole radius oversize (minus == increase of bore hole radius
+0.05mm Difficult to push in by hand and difficult to remove even with a hammer
+0.10mm Difficult to push in by hand and difficult to remove even with a hammer
+0.15mm Easy to press in by hand and can only be easily removed by hand
+0.20mm easy to join by hand and falls out by itself when shaken
+0.25mm falls out by turning under its own weight
