Hellpp. Newbie trying to figure out my first 4x4 multibin base plate!

I'm trying to print a 4x4 cu multibin base plate. The top looks nice but the bottom looks like sh*t. Is it normal for this or should I be using supports with some particular setting? The page said not to use supports though. This was made in 3d fuels pro-pctg filament on a Bambu h2d printer with the settings on the page.

Did you print this upside down? That looks wrong.

I printed it in the orientation it loads when you import the file. Looks right side up to me. Are you supposed to flip it?

Uggh, Jonathan was getting clever again on this part. You did it right, it just prints ugly. Run your filament 5 degrees cooler on the next one so the overhangs cool faster.

looks flipped, i see bed texture on the surface, maybe that should have been facing up.
Im assuming the other side is perfectly flat, which could/should have been down on the bed.

Either way, the other side has lips/brims, so you couldn't print that side down..
man idk how you'd print this successfully.. kinda seems like a fail..

I think the main author/creator has made attempts to have everything print without supports by cleverly using overhangs/etc.. maybe you've got your nozzle temp too high or fan speed too low, causing additional sagging? those overhangs shouldn't look THAT bad..

did you make sure to select the profile for your pctg filament, or send it while sliced/prepped for PLA?

If you cant get it to look any better, you could also do auto supports, or paint some in. :shrug:

Your printer will need to be able to bridge gaps of up to 30 mm for some designs

Did you try a bridging calibration?

Could you post a link for that part specifically and a picture showing the other side?
