Filament Holder 3in1

Made some changes. The tube now holds filament roll better in place and does not require any supports and screws. The baseplate is upgraded so it's a little smaller and actually saves more space, now standard-size filament spools fit more snuggle. Also, the tube has now a little chamfer to hold it snuggle. 

Simple spool holder with 3 possible way to use - stand, wallmount and hanging
