Is 3D printer a toy or is it useful?
Well, if you are building another 3D printer or something like that, you can print those parts.
But is it useful for anything in the “real world”? Cannot you just buy whatever you need off the shelf?
Most of the time you do. But sometimes 3D printer is really handy.
I had a shower shelf that did not stay in place – it travels left and right. There was 1 suction cup coming with it, but it was not enough to secure it in place.
Not just because 1 is not enough. Whoever designed it just did not think it through.
So I have bought more suction cups on Amazon. However, they did not fit.
I could of keep buying other ones hoping that I will eventually figure out how to use them to secure the shelf in place.
But why if I have a 3D printer?
I measured everything and drew this design in OpenSCad:
Here is the print:
Here it is installed:
Everything fits well. 3D printers rock! (for those who are patient, since printing process is very slow)
