Hello, 

I commited this. Each segment is 10 cm long so its fully customizable. You can print it as big as you wish. 

Rails are prepared for 1mm and 2mm (choose prefered print profile) plexi but i have plans to prepare models for thicker ones.

Plugs are designed tightly but if needed, you can always glue them. 

If you have any comments please let me know, its my first ever model, i'll do my best to fix any problems.

Important:

Please check which plug fits you better, and check whether horizontal print isn't better than vertical. With tight plugs you might need to hammer it.
