Just a thought if anyone has issues with feeding filament to the printer head binding a bit. I have upgraded to a little taller filament holder at head and a small funnel pt guide gives the tube a higher arc. Only draw back tube is a little higher and rubs against top side of case . Couple of hoop clips and one solid clip along chain. Going to move a solid clip further down on chain to avoid this… filament changes and loads are nice and smooth now. I found most of the modified holders are to stiff and cause binding…
