I made this model to hold the five Prusa filament rollers that ship with the MMU3. And then mount them inside my (un)Original Dry Box using these dry box mounting adapters.
This parametric model should be easy to modify for many other similar situations.
The base is designed so you can use the original Prusa filament guides or run the filament under the base if you want to try to front-load the filament.
NOTE: The Prusa rollers work much better when the filament is pulled from the bottom of the spool as Prusa designed them.
MAKERS: Please post a picture with comments here of any prints/makes you do from this model so that I can see how people are using it and whether you are finding success with it. Thanks!
