Qidi X-Plus 4 Riser 37mm có khe thoáng “Official” (ReUpload từ Qidi3d.com)

Pending description after investigation. This is merely a place holder. I have primarily placed this here so that it's easier to find. I frequent printables far more than I do Qidi's wiki page, I would imagine that the same is true for you dear Printer. 

I'm amazed that it was published in August of 2025.

Initial thoughts:

(1) Print out of PETG/PET/ABS/ASA/PP/PA.  Or similar meterial that has a HDT well in excess of your expected chamber temp from your prints.  

(2) Thorougly dry your filament, moderately undry filament will behave like improperly calibrated filament and will over extrude causing your holes to be smaller and your print to be a bit larger.  

(3) Accuracy: see the englightening write up by Stew675 in

(4) Given the ammount of supports needed and their nature in that they are generally coplanar, I would highly suggest using a support interface material for your filament of choice.
