Headband Europa V3 (For A4 format)

Hey guys, can anyone please explain to me how do I use punch-hole to make holes in a clear A4 sheet? I am trying to understand through the diagram but little confused.

Hello, thanks for the design. The headband design looks very nice and clean. As you can see in the attached photos, i have some problems, can you help me to solve them please? I use PETG, cura and the ender 3. The 3d printed object doesn't break easily and it has a smooth surface but i am not sure how to fix these empty lines, especially in the back area where the rubber band will be attached. If you have the kindness to help me, i would be grateful. (edited)

Hi Peter, having a big problem with stacks on my Ender 3 printer using Cura Slicer. A lot of it is coming out stringy and week after an overnight print. It’s fine doing one but when it’s a stack it strings a lot

Hi Peter,
we are printing the headbands with our Ultimaker S5 and 2X printers. Unfortunately the results are very unstable when printing stacks.

Single headbands are printing fine with 0.2 layer height and a 0.4 nozzle. 0.3 mm doesn't work very well.

Do you have a suggestion regarding the underlying problem?

Hi Peter
Thanks for your drawings. But can you redraw its for 1mm nozle? EU stacked version
thanks (edited)

Hi Peter, Thank for your great work. I already printed your model for about 400 pieces and distribute to many hospitals in Thailand but some time I still got an issue, could you please add more rides at the position in the picture?

Does anyone have any tips on how holes can be quickly punched into the transparent A4 sheets? The template can be used to mark where the holes go...but how are you all actually punching in the holes? The EU standard double punch has the holes 80mm apart. (edited)

Final Stacked files uploaded. These seems the best overall compromise for most users, giving overall the best results. These are meant for 0.3mm layer, Ø0.4 mm nozzle, and the gap between units is 0.3 mm with tiny 0.4mm wide mini-ridges to act like supports, easily separated after completion. The feedback so far was pretty good, but let me know if there are issues.

Peter, can you redraw the support of the pins to be at least 0,8mm thick? I would like to print with a .8 Nozzle and save loads of time but the slicer won't slice the supports...

Anyone wants to try something new?

Uploaded s set of new 3MF files. Stacks of 2, 4, 6, 8. The files have the new small rods supporting the pins in front, it saves some serious minutes on big stacks!

And also the gap between units is 0.3 mm, but instead of ridges, we are going to use few tiny connecting rods, as to see if this is sufficient, and it if would help a lot with separation after printing.

The files have been opened with Slicer, set correctly with "Detect Thin Walls", set at 0.30 layer and save, so if you use them, the pins should appear and you should have no problem printing. Please let me know if you decided to test some, as if it works well we will make them the default files. Thank you! (edited)

Posted part of this in the “Brasil” thread, but perhaps we can do another experiment here quickly and then compare notes and see which one works best. But first, the story:

Today tried all sorts of gaps on the stacked versions, and absolutely nothing worked! The features in between units (in the gap) simply disappear when you slice! Rods, walls, bricks, whatever - all disappears. Tried several height, all the way to 1 mm gap, but it all disappears!

So I decided this is not a software issue, or CAD issue, but it has to be some setting somewhere. After trying them all (or at least most of them), the one that now seems too obvious but was checked off was “Detect Thin Walls”. I can’t believe it is off by default, but hey. So I am going to make a bet most people have no idea where the button is (or what it does) and so most who have issues with printing the stacks (by seeing empty layers) were simply having the button “off”.

NOTE: You have to switch to “expect” in the upper right corner for this feature to appear in the “Print Settings”!

Once you turn that feature “on”, even the tiniest walls and features appear after slicing! See the 4 pictures attached here.

You can see in two of the shots, the latest trial is with little “Ridges”, which are 0.3 x 0.3 mm. That was with all the “Brasil” stacks and perhaps people will try them. For these stacks here (Europa), made a continuous ridge, going all around with no interruption, so we try this and see which one works best - the interrupted or the continuous. Then we can make all the files the same across all models.

Uploaded are all the new 2, 4, 6, 8 Stacked files, please give them a try and see if you get this to work. I also saved the gcodes for all of them and uploaded them too, see if that could be helpful in case you are not getting them to slice as these pictures here. Let me know your thoughts, I hope this was really the issue and we are over it now.

Can’t put the pictures in the correct order, but look first into those with the menus, so you see the settings and then you see the effect on the model.

Hi Peter, at the stacked versions, between the second and the third one, there is no single layer that makes it easy to seperate. Every other one is perfekt. Maybe you can have a look at it. (edited)
