@Adam_Steinmark . Ok good to know. I will be able to do that tomorrow and will post what I find. Thanks for that tip.
@Christian_Schulz I can see that might could happen. The only thing though, is that those pillars are on one side (very poorly of course), but on the other side it seems they didn’t even try to print, except for maybe two short nubs, and no “pieces” laying around on that side. Thanks for looking into that!
It seems like a couple layers are underextruded, and like others said, some of the pillar layers didn’t stick well. You might try reducing retraction and upping your print temperature.
There are some retraction and temperature test prints on Thingiverse; maybe try some of those before committing the time and plastic to another bust.
@Tim_Visible Thanks Tim. I’ll look into that as well.
@Adam_Steinmark I’m back at it this morning and getting ready to look at the layer view in Cura. I want to share the gcode too, but I’m not sure how to share that here in a post. Sorry to ask, but can you tell me how to do that? Thanks.
@Scott_Sisk upload the gcode file to an cloud storage (google drive, OneDrive or other), then post a link to this file here.
@Scott_Sisk easiest method is gonna be to upload the file to Google Drive or Dropbox and then post a public link to it here.
Edit: @Christian_Schulz beat me to it.
@Adam_Steinmark . Thanks to you both 
@Scott_Sisk Here’s that link to the gcode. https://www.dropbox.com/s/gshlu69noq78z3r/MH_T800_Base_Supported_v5.4.5_Scaled160.gcode?dl=0
Everything looks good from the gcode file, aside from the gigantic brim and super dense infill. There’s a small chance that the filament has absorbed too much moisture and when the extruder retracts and a small blob forms that prevents proper repriming of the nozzle. Since you’re using PETG (which isn’t really the best for intricate prints like this) which is moderately hydroscopic you may want to dry the filament. How long has it been sitting out and what brand filament?
@Adam_Steinmark Thanks for looking at that. Filament is from MakerShape. I’ve been keeping it in a sealed enclosure with a dehumidifier when not in use. I’m using a 4mm retraction.
I think the extruder has a problem. It does not feed properly, therefore there are incomplete layers and therefore does not adhere properly to thin parts.
See if the extruder’s ribbed wheel did not rust? Does the thread with enough strength make you strong? Will the filament roll fail?
Calibrate the extrusion. (search for youtube filament extruder calibration).
@Jakab_Gipsz I will look into that possibility. Thanks.
Yeah this is a bit difficult to diagnose. Were you present during the time the printer was having issues? Was the extruder clicking? Also in addition to @Jakab_Gipsz 's suggestions check to make sure the drive gear in the extruder isn’t grinding away your filament. If it is you should see the drive gear coated in plastic dust.
@Jakab_Gipsz I didn’t hear any clicking. Subsequent prints have been fine. I’ll try to investigate the drive gear, but no visible dust outside. Thanks.
The supports (sorry: thin parts) were weakened due to lack of material and broke down, and then the material went into the air.

Like some said, if u shrink something maybe there will be “walls” that to thin to print. Ur slicer probably can detect thin walls and print em big enough if u enable it. simpel solution if that was the problem. I always take the stl and slice it, after that i load it into ponterface, if there is something wrong u will see it if u look through the different layers. Takes some time but worth it.
The vertical lines are maybe extrusion problems.
Nice project, good luck next time.
@N_Y_NakiYozora thanks much! I’m going to try the suggestions and give it another shot.
@N_Y_NakiYozora It’s not that, I checked his gcode file and thin walls only apply when walls are thinner than 2x the nozzle diameter but he’s having issues with significantly wider parts.
I will say that the weirdest thing it seems is that on the right side it almost looks like it didn’t try to print some parts at all.
On a different note, I wanted to see what would happen if I applied a primer and metallic paint to make it look more authentic. So I used this part ad a test piece. When I get the a good one made, I’ll also smooth it with epoxy and then paint it. But I thought this test looks pretty good despite the orint problems. missing/deleted image from Google+
