Mini Bambu Reusable Spool

I love the original model but I had some issues; Some of the inner filament holes were blocked by what seems to be an unintentional modeling mistake and I wanted it to be more rigid overall to prevent warping in a hot dryer. I personally recommend using more heat-resistant material than PLA if you ever plan to put the roll in a dryer, I've had PLA printed spool holders warp while drying at 40c
