Jack pinch weld adapter for various vehicles

If you have a light car or SUV, you likely have a scissor jack in your trunk for roadside tire changes. The scissor jack lifts your vehicle around the pinch welds, not on the pinch welds. If you like to do your own oil changes or seasonal tire changes at home, using the scissor jack can be slow and tedious. Many people use a hydraulic floor jack which is much faster and easier to use. 

Unfortunately, the lifting end of your floor jack (the saddle) is likely not suitable for use with the pinch welds on your vehicle. The pinch itself is not designed to lift the weight or the car, and thus using the jack's saddle directly on the pinch can cause the metal to buckle or fold over. This adapter is more suited to a flat rubber saddle, but it also works with my original steel saddle (see pictures).

This adapter should face with the OUT outwards towards you. There are two parts, an inner PETG part and outer TPU part. Note: in a bind, the PETG part can be printed with PLA, but it might deform in hot weather. You have been warned.

Print settings for inner PETG part:

• layer height: 0.2 or 0.3
• Infill: 60% Grid
• Perimeters: 5 perimeters

Print settings for outer TPU part:

• layer height: 0.2 or 0.3
• Infill 15% Grid
• Perimeters: 5 perimeters
• Supports: none (the model has the needed supports built in)

This design was inspired by Functional Print Friday's video (33) 3D Printed Jack Stand Pinch Weld Adapter. However, the design of this particular model is entirely my own using OpenScad.

Use this part sensibly. Do not go underneath a jacked up vehicle without the use of jack stands or something else to support the vehicle if it falls. Jacks fail, and adding another point of failure is just asking for twice as much trouble. You are responsible for your own safety and the safety of others that work with you.
