A lightweight interlocking card grid for Space Base

This is a simple, interlocking card grid designed to neatly organize the "shipyard" and "colony" cards for the game Space Base. Unlike nearly all of my other game models, this one does NOT support sleeved cards.

These can be used by themselves but were designed to be used with my Space Base insert [URL] and player boards [https://www.thingiverse.com/thing:6431144]. In particular these connect to the card boxes from that insert (and as shown in the pictures).

These models were designed to print at 0.16mm layer height. If you print at another height the hooks might not work as designed.

I printed these with 15% gyroid infill, but you can use 10% infill if you increase the number of top shell layers by one (or if you don't care about slight imperfections in the top surfaces). PLA/PLA+ works great for all of these.
