This is a remix from DBT85’s Ultralight Gridfinity base (2 wall version). These base plates print super fast and save a ton of filament compared to other base plates. However, fixing these base plates was not addressed. With this remix, I added tiny taps on the side which can hold a 5x3 mm magnet and require 7,1 mm of additional space next to the base. The magnet holes are oversized with a diameter to 5,4 mm. This allows to insert the magnets and removing them super easy. If you don’t like it, you can add a drop of glue to attach them permanently.

Print profile 1 generates a 12x8 units standard 42 mm grid and perfectly fits a HAZET Assistent 177 tool trolley. 10 magnets are required.
This Profile also contains the original connectors. For 12x8 you need 22 connectors. The print profile has 26 connectors in total to have some spare ones on hand in case you drop or lose them.

For the whole 12x8 base grid and the connectors only 30 grams of filament are required. Split to 6 plates, the P1S needs 2 hours and 21 minutes print time.

Print profile 2 is universal and contains a 4x4 and a 5x5 base plate with magnets taps only on 2 side as well as on all 4 sides. To show you the possibilities, there is a “custom” 4x5 plate with taps on 3 sides. If the uploaded models do not fit you needs, I attached STEP files so you can modify it to your likings. STEP files allow to work with almost any CAD software. No nonsense required like with STL files.

If you want a magnetic attachment of the bins, simply embed them in the feet of your container.
