About this 3D model

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.
