Plate with holes

You can use this part to do 180 inverse SNOT and 90 degree SNOT at the same time. The trick is to use jumper plates to take care of the offset, and ensure you fill up with plates so you stay in system. The result is quite sturdy.

To find the different pieces needed for this technique you can search LEGO's online Pick-a-Brick for the design ID's. We link other market places directly on each individual piece page, which you can find below.
