    Unhappy Hollow print. Help.

    Hello all.
    I recently bought my first 3D printer (Ender 3Pro) and I have some problems , tried to print a telescope mounting for a phone but the print came out not too good , kind of flimsy ,and not what I had expected or hoped. (White) .
    I said it's probably the supplied (from the company) sample PLA and switched to a reel of real filament PLA standard 1.75 thickness , and tried a print for a friend but the layers still weren't quite sticking to each other so i bumped the nozzle temp up by 5 C. and it kind of worked after some time but not really .
    Any ideas on what is wrong or how to fix it??
    Anything helps , thanks in advance

    In order to help you could help us by posting your Slicer and slicer settings.

    What temperature are you using on the extruder?

    The creality slicer 4.8.2 slicer is one of the oldest slicers out.

    In fact it is Cura 15.04.6 shown in the image below.

    I have Cura 15.04.6 and on occasion still use Cura 15.04.6 though it is really old. I mainly use PrusaSlicer which is Slic3r with some really excellent upgrades or newer versions of Cura.

    Where I have several profiles configured from my original Cura added to all newer Slicers and they have proved to work great for my current needs.

    I have tried different settings ranging from 200-210 kinda better results after 205 but i am afraid to push it
    Edit(205C is the temperature written on the reel)

    Newest print with 208 temp in most of the print 210 on the last part and higher flow of material up to 111(stock on the printer 100)

    I can't read the wall thickness in the posted image, but that might not be a concern. I see the layer thickness is 0.28 mm, which is very close to the maximum for a 0.4 mm nozzle. Have you tried a smaller layer thickness? Using a layer thickness of 0.2 mm is pretty common.

    Consider also to try a different slicer. PrusaSlicer is quite capable, may have a profile for your printer, is free and easy to use and may shed some light on the problem.

    Ok first of all i am kinda stupid that i said creality cause i had latest version of cura installed and that is what i had used , wall thickness is 0.8 also i tried lower quality(.28) to see if it resolved the issue I had with the dog , witch it did but it came out looking like it's made from spider webs or smth

    Posting the Cura Profiles created and use daily to 3D Print using a .4 nozzle up to .32mm successfully.
    .32mm is max layer height at 80% of the nozzle diameter.

    Give them a try and see if any will help your 3D Printed models.

    For Cura 15.04.6 / creality slicer 4.8.2

    If these profiles work and you want to try PrusaSlicer will post profiles or the Newer Cura versions Profiles

    Sample 3D Printed Model below using single extruder printer.
