Got a new idea for that modular wall we talked about—interlocking bricks that snap together and can be pre‑printed on a CNC machine. If we lay out the tolerances in code first, we’ll avoid a lot of on‑site tweaking. Think you can pull the specs and make the design work?

Sure, let’s pull the tolerances into a quick config file first—0.2 mm clearance, 5 mm wall thickness, 12 mm tall bricks. Then generate a parametric STL with OpenSCAD, feed it to the CNC G‑code, and test a single prototype. We’ll tweak the snap geometry in the code if the test bricks flop. If that hits a snag, I’ll re‑write the function in the shower, but for now just give me the dimensions and a rough cut plan.

Sure thing. Here’s the quick spec sheet: - Brick dimensions: 12 mm tall, 5 mm wall thickness, 0.2 mm clearance between interlocks - Core hole: 2 mm diameter, 12 mm deep (for the snap pin) - Snap notch: 2 mm wide, 1 mm high, centered on the front face - Tolerance for each edge: ±0.05 mm Cut plan for the CNC: 1. Start with a 50 mm × 50 mm stock block. 2. Rough cut the outer 12 mm × 12 mm square with the wall thickness, leaving the core. 3. Mill the snap notch on the front face, then the core hole on the back. 4. Finish with a light 0.2 mm clearance by the CNC toolpath. Generate the STL in OpenSCAD with those parameters, feed the G‑code to the CNC, and run a single test piece. Adjust the notch if the snap feels weak. That’s it.

Got the spec sheet, love the 0.2 mm clearance, I'll spin an OpenSCAD script, generate STL, feed to CNC, but the notch might bite – I'll test the snap. If it cracks, I’ll tweak it in the shower or write a recursive function. Ducks can’t wear hats, but maybe the bricks can. Let’s do it.

Good plan. Just keep the notch sharp enough to grip but not too tight—test it first. If it cracks, cut it back a mill or so and re‑run the test. Keep it tight, keep it fast, and let the bricks do the work. Let's see the prototype.

Will fire up OpenSCAD, cramp the notch to 0.9 mm deep, run the CNC, see if the bricks lock. If it cracks, shave a mill, re‑run. Quick, tight, no drama. We'll let the bricks do the heavy lifting. Let’s see that first prototype.
