Repro generation 2 for the prototype GS Stage 1. Just kidding, this clear piece produced out of resin is not suitable except to aid the next evolution of development to increase quality from the FDM prints of Poly Carbonate. Could use as injection mold of Poly Carbonate.
You used to find the 4- placer wire holders at the auto parts stores. They were everywhere. What we are talking about here is the correct appearing 2-placer wire retainers, that have not been available since the cars were new. These are two totally different things. If you want to buy some generic retainers then have at it. I will be glad to buy a few sets of the reproductions once finished, to help the restorers get the correct parts they need for their cars. That would mean not having to find/take off decent 50+ year old pieces off original engines. Duane
Offering an updated version. New design is an increase gap and small layer lines giving more strength and rigidity especially around the mounting stud which folks had indicated was a cracking/weak point. Smaller layer line also increases weight as more material is used to create the piece. https://www.v8buick.com/index.php?threads/2-wire-spark-plug-retainers-reproduced.383167/
