Pegboard Gridfinity clip-in 2x2 base

Gridfinity 2x2 pegboard base making use of Sy's Peglock system, extending it's modularity by adding slots to the corners of Sy's pegboard mounting plate. The Gridfinity system was originaly designed by Zack Freedman, who originally posted all the Gridfinity accessories at https://bit.ly/3E2NxnZ. The advantages of this version are that the the peg, mounting plate and 2x2 base can all be printed flat, ensuring they are strongest in the direction of stress when mounted: Sy's mounting plate has internal overhangs in this orientation, but required no supports when printed at draft quality (0.32mm layer height) using a 0.8mm nozzle. The base and mounting plate used 35g PLA filament when printed. I tried half a dozen different designs / prototypes before settling on this version: this version was the best combination of rigidity and weight. Once you have printed the parts the base should slide into the mounting plate without any post print processing: it will be stiff, but can be forced in (see photos).
