This block was designed based on the size of my 06 Mailbu, but blocks are pretty universal. The hole is ¼" which should accommodate push pins, or there's a 10mm well for a nut or bolt. I chose to emboss the amp rating on the post before printing mine. The “spaced” file moved the post forward for batteries which have their tie-down lip in a relief. Don't forget that if for any reason you should want the post on the other side, your slicer can mirror the model. Since a lot of parts in cars are HDPE, mine is printed in PETG. Installed 7/7/2023.
