Beethefirst 1kg internal spool holder (Ziro spools)

thingiverse

Beethefirst internal spool holder attachment for Ziro 1kg spools. It utilizes existing stock magnetized spool pin and holder, which snaps into place neatly. Growth of frustration led to creating this design after continuously replacing Beeverycreative's small and expensive filaments. Moreover, I wanted a tidy and internal spool solution. So, the Beethefirst attachment was born. I've chosen Ziro spools specifically because they feature a center cutaway that fits perfectly over the existing spool holder base. The design is quite snug and sits flush with the Ziro spool (54mm diameter with a 56mm lip) to ensure that the reel doesn't sag and touch the build plate at the start of printing. Photos clearly show that the clearance from the base plate is extremely tight (~0.75mm), but it should not touch the plate during printing. ***Important Note: When using a 1kg spool, make sure to keep models away from the right 25mm of the bed (beside the spool holder) as the print head shield may interfere with the spool during printing.***
