Lego City rails storage pin

I made storage pin for my kids for lego city rails. One pin is able to storage for ten rails. There are two types of pins, first for straight rails and second for curved rails. It fits original rails from lego city and from 3d printed rails from pinterest or other pages.

I printed it with normal Creality PLA with 0,6 nozzle. For printing not needed supports, easy for print. Of course it is able print with 0,4 nozzle.
