This is the chassis for Pryds, a model in H0e scale of one of the UHB locos. To improve performance I have made som parts to make the chassis compensated.

I materialise have 3D printed in High detail stainless steel the box for making the chassis compensated and the driverods with forkshaped joint. The thickness of the rods are 0.3mm These parts came out fine and fits with very little filing. The 3D printed rods are a bit broader than the original as evident in the pic. This is my fault and is not necessary. I will file the 3D printed down.

Here is the box for compensation in place in the chassis. The axlebushes are pushed together in the middle. There is no filing or milling nesessary on the chassis. Just drop in.
