donor spool brake

I absolutely love my “filament spool transfer device” I found and printed from another site I will not mention here. The only problem I had was the donor spool would try to spin out of control and make a mess. It also would not keep tension on the filament to make it layer evenly. I went into fusion 360 and designed this brake for the donor spool to keep it under control. You will need a sheet of 3mm silicone from amazon:https://www.amazon.com/gp/product/B09NX8GX5K/ref=ox_sc_act_title_1?smid=ACN
