Exelent!

Easy to print without supports, works as intended

I really like this design. By using an IR sensor there is no extra stress nor wear on the filament. It also accommodates for inserting a PTFE tubes both sides, so it fits nicely on my Prusa Mini. A real no hassle approach.

Wondering how this works with transparant filament, I guess it will work fine because the sensor uses IR, light and thing theatre transparant for normal light tend to be not transparant for IR light.

Thanks for sharing this design!
