I would recommend printing Shaft, Ratchet and Clip in PETG.

How to assemble travel strap protector

Traveling can be rough on luggage. Baggage handlers, conveyor belts, and crowded overhead compartments can cause wear and tear. A Travel Strap Protector helps keep your luggage intact by minimizing the chances of the bagg straps breaking or seams tearing.

Considering the potential cost and hassle of replacing or repairing damaged luggage, a Travel Strap Protector is a print you need to make. It extends the life of your luggage and saves you money. You can focus on enjoying your journey rather than worrying about the safety of your possessions. Hope you liked the product i made :)

Please give me ideas to how to improve the design.
