This is a new version of the polypanel system, originally made by Devin Montes. Combined with Internal Panels, you can produce substantially stronger and more complex structures.
This improves on the original system by adjusting the spacing between the two snap connectors. This allows more panels to fit together in more positions, including half and quarter panels.
A limitation with the original system is that only two panels can be joined together at an edge. This means you could only really build object surfaces and things get flimsy when they get large. This system has some tricks up its sleeve however.
An extra connector space has been added between the two standard snaps, this allows three panels to be joined at an edge using 'Internal Panels'.
There are also 'Centre Joint' and 'Double Centre Joint' panels which have extra connectors for further reinforcing structures.
All the standard shapes from the original system are included: square, triangle, rhombus, trapezium, hexagon, and pentagon.
They are available in four different types, ordered by increasing strength: open, solid, Vopen, and Vsolid.
There are also some special types of panel listed below:
Half a square panel. The 'A' variant has snaps at each end which will match up with standard adjacent panels. The 'B' variant does not have the end snaps, useful in situations where the ends of an 'A' panel do not match with adjacent panels.
Since these panels are not compatible with the standard panels, I have included these half adaptor panels. The A/B variants add/remove the end snaps as above.
Sometimes the connectors can be flipped and do not match up at an edge. To deal with this the half-flip panel can be used with a mirrored connector on one side.
AKA the 'Square Centre Joint', this panel has an extra connector in the centre to join panels in the middle. This is useful for making stronger structures with internal reinforcing panels.
AKA the 'Square Double Centre Joint', this panel has two extra connectors in the centre set at 90 degrees. This allows even further subdivision and reinforcement in a square based polypanel structure.
Square Q A/B
AKA 'Square Quarter' panels. They effectively double the 'resolution' of the standard squares. The A/B variants have the snaps in different positions which will fit for most situations.
Four A/B panels can be added together in different combinations to effectively make every variation of a standard square panel with standard/flipped connectors on each side.
In some cases it is even possible to connect four panels at an edge with this system by including 'Internal Panels'. This way you are able to make cubic frames, making substantially stronger structures and new shapes. On top of this, the 'Centre Joint' and 'Double Centre Joint' panels can subdivide further and make even stronger structures.
This is all in preparation finally for the release of my 'Polypanel Motion System', which will add moving parts and is the beginning of a new construction kit I originally envisioned two years ago when I published the 'Polypanel Shaft System' for the polypanels competition (I have been working on this for a while). The new motion system works on a completely new way of joining parts together so the original 'Polypanel Shaft System' is now obsolete.
I have also added the Fusion 360 files for all the parts so you can adapt them yourself. Let me know if you need any other files e.g. STEP etc.
