Brompton trolley

Hi, I am posting this in case it would be interesting for somebody. I was in need for a trolley bag and because I have the Brompton with the Brompton bag I thought of making a trolley bag out of it. The cost of making it was around 33€ (excluding the Brompton bag) and so far is being very practical for those days that I'm not going by bicycle and I need a trolley bag. The plus for me is that I can remove easily the wheels and it has a rain cover, plus the shoulder strap if I am for example taking the stairs.
Happy to share more details or building instructions if somebody else would like to make it 😉
Also I checked the measurements and in principle could fit into most airlines dimensions for hand luggage (in Europe), perhaps would need to cut here and there in the plastic platform for the most restrictive airlines. But so far no experience on using this build by traveling by air.
