$3.90Catalyst Cube
myminifactory
My wonderful Patreon supporters get this model free! :) (Optional magnets: eight 6x3mm cylindrical magnets) It's a cube-shaped box with four lid pins that are placed into slots so that when the lid slides forward, magnets snap the lid into place, leaving the pins unable to pull directly upwards. The magnets aren't essential, but they're highly recommended for satisfying snappy action! Read the original Patreon writeup here: https://www.patreon.com/posts/catalyst-cube-63778709
