The green one is an original Wera product. I considered reverse engineering the locking function of the original but based on my use case (magneted to the pegboard) I just decided to put some magnets in the round base of the socket holders. The print at the far end had too thick a base and a single layer of 3 magnets for the base but the combo wound up causing the unit to slide down the wall under the weight of the sockets. Current version has only a 3 layer base and 2 deep magnets. IMO it has the right “stickiness” to my toolwall vs the original which is too sticky. I might redesign for 2 magnets on the socket side as well. very important to get polarity right with the wall-hanging magnets and the socket holding magnets or it will be a mess. Use a bit of Kragle under all magnets and give them 10-20n min to dry, especially if you have a hardened steel or otherwise magnetophillic nozzle.
The model should be paused at layer 30 to lay in 6x https://www.amazon.com/gp/product/B0C6G8891X/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
And Layer 68 to lay in 10x https://www.amazon.com/gp/product/B0CCXJQJNF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I'll be adding a 3/8" version soon.
