Description

This is a fuel tank cap that I printed for my Opel Zafira-A. I printed it out of PETG as I understand it can handle petrol vapors quite well. It is printed hollow and with holes (like the brand model) that allow air in or out so that no vacuum or pressure builds up in the tank. No supports needed. I only used a 10mm brim one layer high brim to prevent the piece from curling when printing the first few layers. The O-ring can be printed with Ninjaflex (also suitable for te application) or you can just buy a set of o-rings to fit the cap (like I did). I don't know if it will fit any other car models, haven't tried it. I just kept forgetting mine at gas stations and it just took so long to get another one by order. Infill: 25% triangle pattern Perimeters: 3 Top/bottom layers: 6 Layer resolution: 0.2mm Printing Speed: 60mm/sec.
