Because my LX modification need a little bit more space I've modified Ryoko's Webcam Case.
Modifications did:

• Removed 1/4" adaptor for own adaptor with IR-cut filter
• increased the box-height
• Added gap for the shutter-switch
• Made holes for screws on the top-part

Future improvements:

• Case should be screwed with 4 screws at the top and at the bottom.
