I love what Zach Freedman has started with Gridfinity. However, I don't love having to get my magnet polarity correct without ever making a mistake. This just isn't practical, and I'm a firm believer that magnetic fasteners should always use a non-active surface with the active surface. In other words, steel strike plates should be half of the equation (and they're usually cheaper than magnets to boot!).

To that end, I've remixed a few different baseplate options for Gridfinity to specifically fit 1/4" x 1/32" disc strike plates available at stores like https://totalelement.com. This will also fit 6mm x 1mm strike plates if you're lucky enough to not deal with the constant unit conversion nonsense common in the US... or just order some from China.

Minimal base plates: These minimal base plates based upon the work of RIP_Plo-Koon (https://www.printables.com/model/250550). These are particularly efficient on the filament side, because they can be a full 1mm thinner than the version designed for magnets. These also match my risers that allow you to create tiers of tools and supplies with magnetic capability!

Interlocking base plates: This useful addition builds upon the ideas of Kyle Warren (https://www.printables.com/model/300603). I've also added a countersink for a standard M3 nut. The length is optimized for M3x8 bolts, so there isn't too much overhanging on either side with commonly available bolts. They're a little beefier, but still quite reasonable from a filament consumption perspective. They also raise the the container exactly 1base-u in height (7mm), so they fit the riser paradigm perfectly.

In addition, these can be used the risers to create platforms and bridges! Learn more about the risers at https://thangs.com/mythangs/file/558728

Weighted bases: I've also included a slightly modified version of Zach Freedman's original weighted bases (https://thangs.com/designer/ZackFreedman/3d-model/Gridfinity%20Baseplates-60925) in case you're a big fan or have a specific need.

You can still use M3 screws or bolts in the corners as well thanks to a little extra chamfer action.

As usual...

• No brims or support required!
• Use any filament with an 0.6mm or smaller nozzle.
• Wider plates can curl, so maximize your bed adhesion if you're going big!
• All storage blocks are compatible with all baseplates!
