ČSD M131.1 railbus adaptation for BTTB startset mechanics

Please donate for the discovery of a treatment for Amyotrophic Lateral Sclerosis. ALS has had no treatment for 150 years, since it was discovered.
I made a quick adaptation for BTTB startset mechanics, made first by Petr_Stasny. ČSD M131.1 railcar keychain object 6701682.
The axes for the wheels are in other position of course. You can improved with more details. The buffers are BTTB type.
If you printed in a resin printer, put a photo. I do not start my 3D until next spring.
It is my 9 object which can be printed and use with this mechanics
I allready use this mechanics for 3 railbuses adapted by me: M11, AC Railbus, Ganz 1903,
