15mm in diameter Spool Holder M30x1.5 mounting

This is Spool holder designed for 18mm spools (spool's mounting hole). It is 15mm in diameter so can easily manage smaller spools. Designed for Ender 3 mounting, so you can just replace original one with this, the same way like you did during ender 3 assembling. Designed for 200g spools, but i think it can handle 1kg as well, especially with 100% infill, i used 50% and it came really strong. Main mounting is M30x1.5 (Fusion360) thread. At the end it has little end stop so the spool is nocked dow
