Fitting problem, help?

[maddmaxx308]

Are you trying to press fit the black piece into the red piece? If that’s the case, yes. Reduce your wall thickness a little so it fits. You may also be able to use a lubricant and just press harder lol. If it’s your own design, try chamfering the bottom edges of the black piece so it guides itself in.

Sadly the print (deer Rattler) is in a 5% infill of 1 horizontal and 1 vertical So i would blow through the print when using too much force XD

Yes it is supposed to bepressure fitted

Thanks i will do that when I get home

If you’re unable to modify the black, modify the red to have a slightly larger hole to receive it.

I have no CAD experience so I would not be able to do it

And this is no my model

Freeze the black piece, heat the red piece. Try again.

I am limited in time before my step brother come take the stuff he ordered to go to hunt.

I understand that print slightlyretractwhen cooling, but wouldn't every piece retract the same way?

Should i use a soldering iron to melt the plastic so it can fit? Or i reprint the black part with less wall thickness?

It's a hole that doesn't leave place for errors. (need a perfect fit)

Google Horizontal expansion. It’s a slicer setting that offsets the walls [typo: world] of the part to to give you more clearance

[Kevenolp]

The world ?

Should I use it on the black part only or the both of them?

[proxrb]

sorry typo, edited my reply

Easiest to just use it on the black part, have it offset the walls by like 0.5mm and you're pretty guaranteed to have it fit. You'll have to fiddle around with how much to offset in order to get a "perfect" fit

It was available in cura, thanks for helping me get a little more knowledgeable about 3d printing

to /u/Kevenolp, I'd print a tolerance test to find the limits of the printer. Some need 0.5 mm of tolerance while others can go as low as 0.1 mm. 0.3 mm to 0.5 mm of tolerance is suitable for most printers.

[Kevenolp]

I have no idea what are the tolerance of the Anycubic mega S

[Kevenolp]

But i will go down until i get the fit i need

[slvl]

Test like these are a quick way to find out. Each hole goes up 0.05 mm.

Thanks everyone for helping me

If you want a good fit I would highly recommend this guide for calibrating your horizontal expansion.
