Hook loop Cupler Hornby/Bachmann

I have a smaller than average HO/OO layout. about 14in or 35.5cm in diameter. so the EZ hook loops that Bachmann sells aren't long or large enough to make the corners, the buffers on my models collide or the connection between couplers is two little so that the cars would derail. but I found that the couplers on the Hornby Railroad products like the 0-4-0 Locomotives or the short branch line coaches work great along with the couplers that come with the Bachmann Toby module. so I designed new couplers that could fit with most classic rolling stalk, Hornby railroad, and the UK styled Bachmann trucks. all you need is to screw them in.

when you finish printing you may need to enlarge the holes with a small screwdriver or a knife (Careful). you'll also need to put some 1.75 filaments in the hole for the hook and loop hinge.

I have a new coupler available. this is hopefully more durable and will last longer. here you can use a paper clip as an axle for the hook.
