The adapter is designed for use with small spools in AMS systems (not tested for AMSLite!).
 

If you wish, you can thank me here:   [https://ko-fi.com/bambas](https://ko-fi.com/bambas)  and I will try even harder.
 

Changed: The design has been improved based on recommendations from comments.
1 - The width of the side edges has been reduced to about 5mm.
2 - The minimum width, with the adapter screwed in all the way, has been reduced to about 10mm (now there is no need to print an additional ring :-P)
Thanks to everyone for the tips, I tried to correct all the errors.

With an outer diameter of 200 mm and an inner diameter of 51 mm, the width fits spools from a minimum of 35 mm to a maximum of 59 mm.
Personally, I use it to test new filament so as not to buy large quantities, I buy 200-250 grams.

Changed: Three width straight and angled spacers added to the project for centering the spool. 
Please check the dimensions before printing the project!!!
