Hi there!

I'm pleased to share with you a the modification of extruder's clamp for i3 mega. Stock part don't deal with flexible filaments so I designed replace part. Below, you can find print settings to print this modificated part. No additional parts needed, stock parts only. One thing to do is drill with 2,5 mm tool through the filament hole to calibrate and make more clearance.

enjoy with fiberflex! ;p
