Remixed off of D. Harris's approach for supporting frames without a leg to stand on a surface, this remix is more modular and allows for printing a corner bracket on smaller printers. I built this to support both the edge of the table, but also as a community solution to bracing stackable legs when they release. I will be test printing these over the next few days with some remixed stackable legs to portray how this can be used. My plan is to brace from the four corners in, but the modularity of these files allows for other configurations that I might not be thinking of.
Everything is friction fitting, so tolerances are tight. The main brace may need brim to hold it up, but since you can put it in from the top or bottom into the modular leg mount the brim doesn't need to be perfectly removed.
EDIT: Realized after printing the whole modular tall leg it's a little to tight (still fits, but needed a hammer to loosen it up/get it in) I'm loosening the tolerance and reprinting now.
EDIT 2: After Printing one I noticed there was some room for improvement, so I thinned the walls for less filament, and made versions that allowed for only the connections that you need. (this also makes room for dice tower and component cups. I'm not certain the edge brackets are necessary with how sturdy this makes the table, but I'll leave them up for now.
