fantastic, i can imagine people 3d printing wheel nuts and bolts for cars lol.
Iv noticed that in tinkercad making thread holes in a shape results in size issues with the threads. Doing a metric m8 hole with threads the hole was so small only a m6 screw would fit in it properly.
Trying again now with thread and hole size for m6, m8 and m10 to see how it ends up.
Why this happens?

So if you have a 0.4mm nozzle you need to add roughly. .4 to the diameter of the hole to account for the extrusion width. I normally model in the printer tolerances during modeling so for an fdm the model would be different from my resin printer which I don't model in the tolerances.

Measure it print a cylinder with a known inner diameter of say 10mm then measure the inside. It will likely be 9.x mm. After that compensate the model and reprint. You can do this with a couple of quick 5 min prints.

ahh good idea, at the moment iv got these 3 being printed:
3 cylinders with m6, m8 and m10 size. will see how they turn out.
Did this today, printed 3 cylinders with holes inside, a 6mm, 8mm and 10mm.
These printed out close to perfect in size so looks like there is an issue with printing out threadded holes which end up almost 2mm smaller than they are supposed to be.

So there is your answer, for threaded holes add 2mm to the bad boy
that does kinda make sense to be honest. think about the additional inside bore being taken up by the thread depth. I can't remember exact figures on mine but I have them somewhere and came up against this when making a replacement part for my shower.

Well that makes sense, if thread hole size is constantly off by x amount then i guess compensating for it is the way to go. Will do few more test cylinders with threads around 1.5mm oversized and see how snug the screws are.
Good stuff though these 3d printers, the possibilities are endless

fusion is big boys toys, our man here is just starting out his journey
Eventually he will find something that isn't simple in the likes of tinker and end up being forced but thought edge him in gently haha, just starting out on my journey. will need to try some software like autocad or fusion360 and see if threads is more accurate there.fusion is big boys toys, our man here is just starting out his journey
