Today it is complete neck and front fork covers.

First of all, I would like to point out that all today's parts are very small and weak. Therefore, exercise caution when manipulating.
Be extremely careful during the assembly itself and work slowly and cautiously.
If you manage to damage or break some part despite being extra careful you should "weld" it with a soldering gun rather than gluing it with super glue.
