My best advice is if you are having problems, use rubber duck debugging. It feels a bit silly at first, but it really does work

I've bought a 3D printer (a 3DCSTAR P802-MHS) and, wow, the assembly instructions were atrocious, if you've already built a 3D printer or three you probably wouldn't have too many issues, but if it's the first time you've done this, it really is like trying to icescate uphill.

This question is a little more advanced than this tutorial, but hopefully somebody will know and answer anyway. How do I make a curved pipe in tinkercad?

The ones pictured here could be solved usung any of the standard algos, they do make sudoku cubes with the numbers all the same colour, on the same coloured background (needless to say, they take a bit more work)

Really good 'ibble. Although I am not a fan of Potter (in any sense, of the word LOL), but another little detail you could have added is a little gold leaf on the spine (or all over if you prefair). It's quite easy to apply, but really does add a touch of class ;^>
