My Shop bought Sports roller was too long for my sports bag and it also would not roll on the floor for my foot. So I designed my own.
This Sports Roller will fit in your sports bag plus it can also roll on the floor to use with your feet when needed. The roller is very strong has a smooth roll action as it has 608 Bearings in the roller. As it is not to large it gets in to all those places your floor or larger roller cant.
There are two rollers to chose from, the Spiky (If your hard enough) shown in Orange and the Spheres shown in Purple.
If you print one please post a 'Make" I would love to see some other colours etc.
I printed mine in ABS as that is supposed to be more resistant to oils and sports people could have oils etc.on them. I have been using mine for over a year now and it still works and looks like new. (The pictures are of my year old ones, not fresh off the printer ones)

1x Steel 8mm threaded rod, 320mm long
2x M8 Steel Nuts
2x 608 Bearings

The Handle is not threaded but still screws on to the steel threaded bar, It locks in tighter once the bar gets to the M8 nuts at each end.
The bearings and the M8 Nuts might need a good push to get them in.
