Carpet Cardboard Tube Caps

thingiverse

This is a cap to use on the ends of the cardboard roll that comes with carpet. I got one of them from my local carpet place and cut it into 4 foot segments to store DIY battle mats but you could use this for anything I suppose. I measured mine out to have a 4" inner diameter and about 5mm thickness to the tube. CarpetRollTop: This one is for the top of the roll and is meant to be removable. You could scale it down a touch if you want it to be tighter. CarpetRollBottom: This one is a press-on glueless cap for the bottom of the tube. Once this one goes on it's very hard to get off.
