Customizable eSun eBox to Filament Tube Coupler

thingiverse

This item will allow you to attach filament tubing to your eSun eBox Filament Storage Dry Box. It has been tested for 1.75mm filament and may work for 2.85mm filament. All connections are push-fit. You may attach the item for the filament to exit diagonally up or down. Simply push into place with the bottom shell, or the top shell. Customiser settings: 1. tube_od - your filament tube outer diameter - add some leeway if required (suggest 0.05mm) 2. channel_d - the filament channel diameter - note that the bridge's narrowest diameter is 5mm, so space is tight! - setting this to 3.1mm will allow for 3 lines when sliced with an extrusion width of 0.45mm 3. coupler_ln - length of coupling 4. back_lip - height the back plate sticks out - this helps hold the lid closed - if set too long, it will interfere with lid closure You may use LLDPE John Guest tubing (filter system tubing). In my tests, I found that filaments have a tendency to stick to the 1/4" LLDPE John Guest tubing (~1m length), causing extruder skips at speeds > 8mm/s (volumetric rate > 20mm³/s). 3/8" tubing may work here, but LLDPE likely loves PETG filament too much. If you have an MK2.5/MK3, you might find this useful: https://www.thingiverse.com/thing:2959148
