This is a quick fit filament oiler for when you are printing PLA on an all metal hotend. It is split for easy fitting with printed hinges and is held together with an elastic band.

Fit some sponge or cloth, add a few drops of cooking oil, close over your filament and secure with an elastic band.

The print in the photo is a bit rough as this printer needs a bit of work.

You can also use this as a filament cleaner/filter if you don't add any oil!

Printed this at 30% infill, PLA, and the tabs were so weak they didn't even come off the bed with the holder, they just snapped right away. Maybe you could increase the connectivity between the tabs and the holder pieces?

What layer height are you printing at?

Primary layer height at 0.2mm, 100% first layer and 120% first layer width, at 35% speed. Using S3D for slicing.

Did the hinge get printed on two layers?

I'd guess they are printing too thin or too squished into the bed (but its only a guess).

Try printing @ 0.3mm layer height so the first layer is thicker.

I haven't used S3D so can't say if that has an affect, but I'd say try slic3r or Cura and see if that makes any difference.

Thankfully it doesn't take long to print so you can try a few different settings.

Nice design, I like that I can add oil or replace the sponge with out removing the filament if needed. Thank you for posting your design.

I have never heard of adding oil to PLA for all metal hotends. I've been using an E3D hotend for over 2 years and rarely get jams from PLA.

It may be related to the brand/manufacturer of filament used.

I'd never heard of it too until I fitted an all metal hotend and started trying to figure out why my extruder was skipping constantly. There is a long thread on the subject on the e3d forum. I ended up 'seasoning' the hotend with olive oil and that instantly made things better but I also read that the seasoning wears off and the oiler helps to add a tiny amount of oil to keep things moving.

At least thats the theory!

Which version of the E3D hotend are you using? I had a v1 when it was first released and it was metal all the way through. I now have a v6 and it has a ptfe tube that goes well into the heatsink of the hotend. With my v1 I used to get jams. Then I got a bigger spring for my extruder and tweaked the temps alot more and it worked great. The v6 is awesome, unless I screw up the temp really bad it will extrude nearly anything without a jam. It even works well with TPU which I have heard is a pain in the ass for more people but the E3D v6 prints it very reliably.

Chimera - It has a long metal heat-break and the PTFE doesn't go into it.
