GridLink Genesis, Custom Panel System w/Reinforcement and Mount Support, GLH6020-050R4.15M4.85

GridLink Genesis™ is based on a 60mm square, 20mm thick (6020) base tile. It is the most structural, strongest and most insulating of GridLink series. At the 5012 or 6020 level, GridLink is more than capable of serving the same purpose wooden boards might for many use cases. With 20mm of mating surface and connector socket covers acting to help align connections, GridLink Genesis really can be the starting point for many and various great builds.

Hidden fastener connecting parts in this size are available with or without mounting holes, grooves and channels for reinforcing rod. The parts in this listing are full featured, with channels for 4mm steel reinforcement rods (optionally 5/32 TIG welding rod) and self tap or manual tap M5 mounting holes. To review other options, see:

These have a very slightly relaxed 50 um tolerance, but they should still fit very snugly and may require a mallet to hammer them together. If too loose, try temporarily increasing filament flow rate by about 0.5 at a time until tight enough. If too tight, reduce it. 
 

WAIT, THEY DON'T FIT !!!:

The covers that hide the fastening tabs on GridLink Form and GridLink Genesis, create some build complexity. No part can be added, connecting to both a tab and a socket at the same time. So you have to select parts and build in an order that does not require this.

The best strategy is to start with an all-tabs corner. Then build outward such that you are always creating a complete rectangle, or an inside corner that is fully composed of either tabs or sockets (never both). Any ‘L’ shape with both tabs and sockets is a show-stopper. This is why there are only two of each 4 possible corner pieces (for different widths) in this set. The missing corner pieces are the ones that can't be made to work.
 

AACK!  I NEED TO GET THEM APART:

Hold the larger part of the combined piece over a strong table, with the smaller part hanging over the edge. Make sure this part over the edge is oriented so it can come off in the downward direction, and make sure its tab is not over the table. Clamp the combined piece in this position if possible. Then tap gently (and possibly more firmly) as near the edge to be separated as possible.

You may want to download and print this helper tool, which is basically a tile shaped punch that can help mallet them back apart. Once you do a few of these, it becomes much easier.
 

A QUICK TEST:

The simplest panel is just one of each 1x1 corner piece… This will make a 100mm (~4") square, and is a cheap and simple test run to check the fit of pieces as printed by your printer. It's a good idea to get something small fit together, before printing a larger set.
