This is an adapter to connect the Magnetic PTFE Joiners by Line Arc Line to an EIBOS 3D Series X: Easdry filament dryer. It supports the “No Offset” type of PTFE joiner.
It uses screws instead of additional magnets for the magnetic connection.
| Note: This project requires drilling into your filament dryer |

Required Hardware
| Qty | Name | Sourcing |
|---|---|---|
| 3 | M3x10 Countersunk Flat Head Cap Screw made out of ferrous metal (magnetic). If ordering from Aliexpress pick the black ones (not stainless). | Aliexpress |
| 3 | M3 DIN934 Hex Nut | Aliexpress |
Quantities are per unit. The dryer has 3 filament exit holes. To cover all holes multiply the quantities by 3.
Printed Parts
| Qty | Name |
|---|---|
| 1 | EIBOS Easdry PTFE Adapter Base |
| 1 | EIBOS Easdry PTFE Adapter Filament Guide |

Printing
Print the parts in the original orientation. All STL files are pre-rotated for printing. The PTFE Adapter Base has integrated supports that need to be removed.
- Material: PETG, ABS, ASA, etc.
PLA not recommended because the filament guide is partially inside the dryer and may get deformed from the heat - Extrusion width: 0.45mm or 0.65mm
- Layer height: 0.2mm
- Perimeters: 3
- Infill: 20%
- Supports: No (integrated)
Assembly and Installation
Step 1
Remove the support material from the PTFE Adapter Base. Push the PTFE Adapter Filament Guide into the Base so that the Filament Guide pokes out of the back of the Base. You may use superglue to permanently bond the parts but it isn't necessary. Be careful not go spill any glue inside the hole of the Filament Guide.
Step 2
Stick the part through the rubber seal of the dryer until the Base is flush with the filament dryer.
This step is a little finicky and you might accidentally push the rubber seal out of the hole. It helps to twist the part back and forth while pushing and holding the seal from the inside to prevent it from getting pushed out.
Step 3
Align the part as shown and hold it tight. Use the holes of the part as a drill guide to drill 3 holes into the filament dryer with a 3mm drill bit. Clean up the holes on the inside of the dryer if necessary.
Step 4
Fasten the Adapter with the M3x10mm countersunk screws and nuts. The screw heads should be flush with the printed parts.
Step 5
Test the installation. Make sure that the magnetic coupling is sufficiently strong. I recommend using N45 magnets for the PTFE Joiner since this is a magnet-to-metal connection instead of a magnet-to-magnet connection. If the magnetic connection is very weak your screws may not be made out of ferrous material.
Test the filament path by pushing a piece of filament through from the inside of the dryer and check for obstructions. I'd recommend using PTFE tubing with an inner diameter of ~3mm. If using a smaller inner diameter you may have to chamfer the tubing.
