For casing designers-to-be:
Based on Gert's technical drawing and photo's, I created a SolidWorks2010 assembly with model-B componets which I found on several electronics component sites. I tried to choose them as accurately as possible, not sure however which will be exactly on the "real thing". However, measurements may easlyly be changed in the SW model.
SW-assembly, parts and IGES in:
Use & change them as you like; can't wait to see well-designed casings for different target-groups, applicatios and environments!
If needed, I'll be glad to "save as" different formats.
