Bambu Spool Lock narrow

Remixed from original for the second time, first try here https://makerworld.com/en/models/171292 is wide enough to not work on external spool holders.Print this one if you use external holders that use center hole to mount. I use dryers and spools roll on external diameter so I didn't check. Prints good in PLA, I changed the base so it is entirely flat to make printing easier without fail Thanks
