TSB-2555BXZ3 Side-Address Shock Isolated Saddle for BM-700 / BM-800

thingiverse

This is a custom combination saddle and post designed specifically for mounting a Transound TSB-2555BXZ3 capsule within a generic Chinese microphone body, such as the BM-700 or BM-800, for optimal side-address use. It should print accurately without any additional support on most standard printers. The mounting holes are precision-cut to match perfectly with the holes found in all BM-700 and BM-800 derivative microphones. However, it's worth noting that some of these microphones only have two of the four holes tapped into their upper plates. The holes are threaded to accommodate M2.5 screws, which will work even if you decide to use only two screws, but be aware that fully populating the mounting screws may require purchasing a tap and tap handle. The mounting holes are designed to take shock-isolating grommets commonly used for RC servos. Du-Bro #115 "Natural Rubber Grommets for Small Servos" or equivalent work perfectly well. The stock screws provided with the donor microphone will likely be too short due to the additional thickness of the grommets, so I recommend using M2.5x6mm screws with M2.5 washers to ensure a secure mount. This is the shortest screw length I would consider using. For this custom mounting solution, the wires run through a 3mm diameter hole in the middle of the post, providing ample space for the wiring. While there's limited room for wires, you shouldn't need more than 3mm to complete the job. Neumann uses equivalent 30ga wire on their microphones, and I used 28ga wire, leaving some wiggle room. To attach the capsule to the saddle, use an adhesive like E6000 for a strong bond.
