30

Part of the GBC standard is accepting batches of up to 30 balls at once but a lot of modules actually fail at doing so reliably and consistently. "30" was initially designed to easily test compliance with that part of the standard. It collects exactly 30 balls and dumps these into the next module in one batch. To achieve this, it uses two tippers. The first one collects three balls and passes these on the second one in three parallel lanes. The module was designed in 2019 and had it's first appearance at a show ("Dülmener LEGO Aktionstag") in late summer that year.
