Digital Encoder Base Problems

Hello everyone,
We’ve been having some issues with our Digital Encoder (Item Number: E4P-360-250-N-S-H-D-B) base mounts, as the tabs keep breaking off and making it impossible to mount. We’ve tried 3-D printing copies, but those prove just as flimsy. If anyone has any ideas on how to make the assembly more secure, it would be greatly appreciated. :confused:
