After not being able to find a replacement at the local Pick-n-Pull. I designed and printed a cupholder insert for a 1997-2003 Ford F150. It looks exactly the same from the top, however, the underside is a tiny bit different in order to accommodate the 3-D printing process. Very pleased with the outcome. Used Fusion 360 for the modeling.
Hatchbox TPU White. Print time was around 12 hours but it was worth it, came out first try and fits great. TPU is a little harder than the plastic ford used but fits exactly the same.
