A huge collection of bridge pillars for märklin h0 bridges.
The model is inspired by the original märklin pillars (7064/7065/7066).
The lid is printed separately and can be used on top as lid or between two sizes of wall as a connector. 
The entire model is modular and can be easily stacked together. For better security, superglue can be used to attach them together.
The walles range in size from 3mm to 15mm in 3mm steps and from 15mm to 135mm in 15mm steps. Further required sizes can be achieved simply by combining the existing sizes.
(If there is a high level of interest in a particular size, I will add it upon request if necessary)
