Top Spool holder for A1 mini

I struggled to print TPU due to too much friction of the filament. So i designed this spool holder to add the filament with as little friction and as directly as possible. This spoolholder does not need any screws to attach. You can simply stick it onto the printer. The fit is not perfect put it is stabel enough for a 1kg filament spool. Since this spool holder i had less dificulties to print TPU. Also it gives the printer a smaller footprint if you want to use an external spool. Feel free to optimize my printing profile or the design itself.
