For larger architectural models, RC vehicle frames, or structural jewelry components, the \u003cstrong\u003e3mm–10mm OD\u003c\/strong\u003e range is more common. If you need a tube to slide over a wire or rod, choose an ID slightly larger than the wire diameter — remember ID = OD − 0.4mm for all variants.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow many pieces are included per order, and can I order in bulk?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\n        \u003cp\u003eEach order includes \u003cstrong\u003eone tube of 500mm length\u003c\/strong\u003e in your selected OD × ID size.
