I just got a new 0.5kg PLA filament spool and needed a spoolstand for it. I didn't have any metal parts at home, but I couldn't find an entirely screw free filament spool holder.

So I made everything printable. I just finished it after about 5 hours of work. Hope you all like it.

It was very careful to make it printable without support structure.

Depending on how well you printer is calibrated with regards to the bridges you should have no problem printing this design.

The design requires to be glued onto a surface. I am using the powerstrips from tesa (see picture). These should have no problem holding it. Alternatively double sided tape should do the trick.

In parts that require bridges to be build use a small file to remoove material that is hanging into the tube. You can see the process in the pictures.
You need to print the stls with an _x2 behind the name twice to be able to assemble the structure.
The rods fit snugly into the corresponding tubes. In my case I didn't need to use glue. But be careful once a rod is inserted into a tube it is almost impossible to remove it again. So I would recommend printing all the parts and laying out each tube before you jam them together.

Minimum print platform is 14x14cm
