About this model

I found my 250g spools were too small to fit on my Artillery Genius spool mount, so I created this adapter to fix that. This is a simple adapter to convert your smaller filament spools (less than 1kg) to the typical 1kg sized spool. It's the typical 200mm diameter and 60mm width when assembled.There is a spacer included which can help with some spools rotation/fit, but is not necessary for most. Threads are M45x4.5 Left Threaded (reverse threaded) to keep the spool from potentially unwinding when rotating on bearings (ie.. if you had a thick spool being held). Tolerance on the threads are set to 0.2mm so there should be no issue with fit. No rafts are needed and printed on my Genius with no brim (but there is room on the Genius for one if you need.. but I had no issue with bed adherence).
