Transmitter Mount for Bass Guitar Strap (Ver. 2)

About: 

My friend is in a German punk band and asked me to help find a solution to keeping his wireless transmitter on his bass guitar strap. This is the 2nd version I came up with which has a lid instead of using velcro to secure the transmitter. In the picture the model shows my name and logo that my friend asked for but the file I've uploaded here is blank. 

Dimensions:

• Inner dimensions (transmitter size): 96 x 72.2 x 28.5mm 
• Strap width: 76mm

Notes:

• The lid slides on a little tight but after you slide it on and off a few times, it loosens up perfectly.
• When removing the lid, do not put your fingers on the tabs that go on the guitar strap and put any pressure. They more than likely will break no matter the material.
