If you want to set up the buffer without the original connection to the printer, the buffer is not secure.
A second stand is required for this. In order to be able to use the original stand (which is already used on the front) at the back, you need an adapter. The stand is screwed to the adapter in the same way as on the front.
needed tools:
2.5mm Allen key for M3 screws
needed parts:
- Leg-adapter (1x) → (this part)
- Buffer-leg (1x)
- M3x30 screws (2x)
- M3nS nuts (2x)

assembly:
- Insert the protruding parts of the Buffer leg into the openings in the leg-adapter. Push it all the way in.
- Insert the two M3nS nuts into the small openings in the leg-adapter. Push them all the way in.
- Slide the buffer plates into the leg adapter.
- Insert the two M3x30 screws into the openings on the side of the leg-adapter. Tighten them up. (If the screw doesn't go in, make sure all the holes align with the plates.)
- complete! You now have a secure buffer.
