Spool Holder

i have bought a Chinese 3D printer with a spool holder that consists of a 20 mm PVC pipe 11 cm long, this was good since the spools where small in size, but once i bought a filament and the spool size was big and thin, the spool usually falls off and causes my print to fail several times, so i thought of making something to solve my problem and i saw an example on thingiverse, i love it but it wasn't the size i wanted, so i decided to create my own and share it over here. hope you guys like it.
