[sdiy] Parts going out of module panel

[Matthias Herrmann]

Just as a side note regarding the actual front panels, the sdiy.info/wiki article states:

“If the Doepfer specification is followed, or rails with sliding nuts are used, elongated holes are not required. These are useful for non-standard panel widths and to compensate for for manufacturing tolerances of the panel width or hole position. They help to fit the modules flush against one another.[14]<https://sdiy.info/wiki/Eurorack_DIY_panel_components#cite_note-oval-14> In a double width case, there will be a gap where the two threaded inserts meet, unless e.g. single 168 HP tiptop Z rails are used.[15]<https://sdiy.info/wiki/Eurorack_DIY_panel_components#cite_note-15>

Oval holes were originally for mixed Analogue Systems (AS) and Doepfer systems. The AS holes are 0.2" from the panel edge and the Doepfer holes are 0.3" (7.62 mm) from the edge. The oval holes were originally used to allow these modules to be placed in the same threaded rows without having the 1/2 HP gap that would otherwise result. These days the oval holes are mostly just centered on the Doepfer spacing.[14]<https://sdiy.info/wiki/Eurorack_DIY_panel_components#cite_note-oval-14> “
To my knowledge the “oval holes” are actually meant to be double-D holes. They where originally used in the Eurocard rack-cases to take plastic or metal screw holders which would snap into them. If so they would have nothing to do with non-standard panel widths or different modular standards. The distance of the mounting holes is clearly defined, the tolerances of panel widths just depend on the manufacturers capability.

here is an example of such a screw holder:

Top tip! Thanks! :-)
