The harsh angle which the filament exits the Eryone filament dryer has always been disconcerting. Also, every option for where the PTFE tube can exit are located towards the front side of the dryer which might not work well for everyone’s setup. Changing the direction for the filament outfeed can reduce/simplify the path for filament and tubing, reduce the drag on the filament, clean up appearance, and even retaining the ability to easily view the hydrometer display.

A 3D model to address these issues of the Eryone filament dryer was not available. However, there is a model that was designed for a Sunlu brand dryer that possibly could have fit. The general aesthetic of the design is appealing so a design was created based off it to fit the Eryone filament dryer. It also accommodates hardware (fitting and screws/bolts) that were available at hand.

The 3D model "Sunlu dry box filament guide" by YogieBear used for inspiration can be found here: https://cults3d.com/:1670328

• This 3D model drastically decreases the angle which the filament has to bend prior to exiting the dryer.
• This 3D model allows a wide degree of angle for the filament outfeed.

NOTE
 -This 3D model may fit other series and/or brands of filament dryers but is untested.
 -Be mindful of materials used for this print as the application is for a heated device.

Hints:

• This is an easy print; no supports needed and just about any print settings will work.
• Be sure to dry fit (use of temporary adhesives or tape can help).
   Only once satisfied with the location should one proceed to drill any holes.
• This 3D model can be used as a jig or template while drilling the required holes.
• It is easiest to drill a single mounting hole, insert and tightening mounting bolt/screw completely, then move to drilling the next mounting hole.
