Description
Above my printers I have a shelf, that's supposed to be 28mm tall. I decided to place my filaments on the shelf. Upon measuring I discovered these shelves are actually 27.2mm tall.
The shelf isn't quite deep enough either, so I relocated the front feet from the holders to be a couple of cm back and built in a small step down into the top of the model.
I've included the STL file and also the F3D file, just in case you want to change something. You might notice a circle taken out of the inner side of the model. This only serves as a way to use less filament.
In the pictures, I've not used any supports. This isn't a great print, so I'm printing the last 4 now with supports just to maintain the circular pattern. They don't have to be perfect, they just have to work.
The model has a thread for an M10 connector, getting it screwed in was slightly trickier than I would've liked, but I found clamping the connector into the thread while using a wrench was pretty easy.
I have the 5 filaments next to each other, each one sitting on the supplied spool holders from Prusa. I found that using around 20cm of PTFE out of the bottom of the PTFE connector works well, and the overhang produced from the MMU unloading isn't terrible (there's a picture of this)
I hope you like this. Works well for me. Let me know if you have any issues!
