Vacuum bag brace

These braces are used to prevent the spool from being crushed or warped due to the vacuum pressure, which can occur during long-term storage. Shaped to fit snugly around filament spool to provide even support. They are designed to fit the bambu reusable spool and Esun carboard spools and the even most 3D printed ones. Example in the picture. You either use 4 and have a somewhat decent vacuum or if you want it to be vacuumed well I would suggest using 8. Print profiles attached to this. The Braces are 4 wall thick to make them strong (Could reduce it. Up to the user). They have been designed to be curved on the edges to avoid puncturing the bag.
