Do you have a 3d printer?
If you don&#x27;t have, your urging advice is pointless.<p>I know how to measure, drill and tap, saw and file. Everything you said I do, and do well, and probably much better than you do.<p>I have also lots of 3d printers, I volunteer to teach children the basic making techniques and also 3d printers.<p>One of the best thing of 3d printers is printing tools. I can print a vice accessory so I could adapt a 6 euro vice to aluminium plates.<p>Doing so with only metal will take 8 times the work and time. I could design a piece and multiply it by 100, and not spend 100x the time doing it, the 3d printer as a robot does it.<p>My professional jigsaw machine&#x27;s motor died, so I replaced it with the entire assembly of a hand drill tool that I bought for 1&#x2F;10 the price the original manufacturer asked me. I designed and 3d printed the support-adapter to the saw in ABS and aluminium. It took me 2 hours cutting and reusing the old axis in the new machine. The original motor had to be imported and was very expensive to transport because f the volume and weight.<p>Now the machine works much better, as the motor weights 6 times less, is smaller, is inverter, with variable velocity, and more powerful.<p>I 3d print my own 3d presses and my own CNC machine:

I only cut small pieces myself, it takes a lot of time to do it manually,and I have great tools.<p>I send it to laser or water cutting, but the design must be perfect before sending and 3d printers are great tools for that.<p>&quot;Until then, no amount of clever technology will overcome the basic materials science that prevents FDM machines from being useful.&quot;<p>Until then, your prejudices will blind you.<p>Lots of the great things of 3d printers have nothing to do with technology, but with people.<p>I teach children, and every one of them could create as I do. I teach them the jigsaw hack and the next week they surprise me with their own hacks, inspired by me but done entirely by them.<p>Not only that, but I can download their designs and replicate it with zero effort, I just press &quot;print&quot; and go take a nap, when I wake up, the thing is done.<p>Is an incredible tool for collaboration.
