Printing small heat recover with hexagon holes

[SSJ]

Hi

I hope some of you can give me a hint on how to solve this problem:

I'm trying to print these samples (see the attached files) on a CR10s4, with PETg,
but at the one end the hexagon holes gets blocked.

Do you have any suggestions on how to get rid of the blocked plast on the one side?

Is it maybe possibly to make a support wall at the 2 sides?

Hope some of you have a good advice

I am confused as to what side is on the build plate.
Can you set this up to print then click file > save factory file as and save the file. Then attache it.
This will allow anyone helping to open the model as it is on your computer with all of you setting and even print it if we so desire.
Thanks

Thank you for the answer.

I have attached the file. If you need more information please tell me.

Best regards

Ok, first thing, you need to flip the model so the holes are down on the build plate. To do that hit control-L and the click on the hole side of the model and it will put that side down. Now you can remove the Raft and support checks so they are not generated you no longer need them. Looking at the model there is insufficient material to close several of the holes along the perimeter but I assume you are aware of that.
Other settings that need to change if using PETG is to remove all the cooling. PETG does not need the fan. Not sure if it matters but I set minimum extrude length on the Advanced tab lower left to .1
Give that a shot and see how it does..

Thank you for the reply

I have also tried to print it with the holes down at the bed, like you suggest, but then it take 4 times longer to print.
We are testing this FDM print method because we consider to use the technology for the first production series, which will be around 800 pieces the first year. Also the final model would have a diameter of 375 mm, so we need to optimize the print time.

unfortunate dont the new settings works, i do still got stringing and over extrusion at the end of the course
