Spark Plug Holder for Reading, Indexing, or Setting PlugsI had someone reach out to me about a spark plug holder for setting reading plugs, so I designed 2 different styles. Plugs can be inserted in either direction. Both can be customized with your firing order, name, and engine style. Will be 3D printed in PETG for oil fuel resistance and is available it multiple colors. Large is 3 rows of 8 plugs, Small holds 8 plugs in the correct cylinder layout.

Great shelf
Color: 1set, Size: 32inch, Color: 1set, Size: 32inch
Looked great in home office. Easy to assemble and not too difficult to install. Hardest part was measuring and getting two shelf sets to align properly on the wall but would have been super easy with just one. Will need a drill for the anchors.

Gorgeous shelf
Color: 1set, Size: 16inch, Color: 1set, Size: 16inch
Gorgeous shelf! I know it’s not real wood but you can’t tell the difference and the price is right! Pipes are beautiful too! My dad put this up and had a little trouble aligning it up with the holes so make sure you have um right before you start drilling them.

Not REAL wood - particle board with veneer - but still beautiful.
Color: 1set, Size: 24inch, Color: 1set, Size: 24inch
Came on time, easy to assemble, relatively easy to install. Metal rods are actually metal, which is nice. Flanges are good quality, very nice rustic look.
Shelves are less wonderful. They are definitely not real wood at all. They are cheap particle board with veneer. I would not have purchased had I read more reviews, BUT it is still beautiful, sturdy and does the trick. We can always cut our own shelves if we should so choose and re-use the very nice hardware.
4/5 for misrepresenting as real wood, but 5/5 for functionality and aesthetic.
