Pushrod Holder for Small Block Ford V8

My old Ford 302 V8 needs new head gaskets, which means the heads have to come off, and to keep the pushrods from just rolling around the garage I decided to make a holder to keep them corraled. I'm too lazy to drill 16 holes in a wood block, so I designed this in TinkerCad and printed it on my AnkerMake M5C. It's just a rectangular block with 16 hollow cylinders in it. Designed for pushrods up to about 9.5mm in diameter - if you need a different size, you can scale it accordingly. I labeled the front using PrusaSlicer's new text feature so I could put the rods back in the same positions. 

TinkerCad seems to have lost the design somehow, so I'm not able to share a link to it.
