This model was the winning entry in E3D Toolchanger STL Design Competition April 2019 https://twitter.com/E3DOnline/status/1119308448565473281
I have created a chest for 3D printing enthusiasts to store all of their valuable treasure, i.e. NOZZLES! You can store up to 15 nozzles in the chest. Nozzle holes fit standard E3D V6 6mm threaded nozzles. The model uses 4 filaments and prints in place. The first three filaments used are standard PLA and the fourth is a flex PLA. I used the flex PLA in four ways:
- Flexible chest hinges
- A flexible lip around the nozzle hole to allow you to easily push in and pull out nozzles
- Friction fit for nozzle labels
- A non-slip base
You can also print this in a single color of PLA if you do not have multiple material capability.
Note: The multi colored print photographed above is an older version, but it is pretty close, just a few tweaks. However, the current version has been printed in single color and confirmed to function correctly. Also, please excuse the under extrusion and missed layers (4 Silver, 1 Gold. 1 Brown), had a clogged nozzle early on and still waiting for my MMU2S upgrade. Not going to attempt a 20hr print again until I running the 2S.
Other Multi-Material Prints

Sliced using Slic3r Prusa Edition v1.43.1
Print Time: ~20hrs
- Perimeters: 2
- Top/Bottom Layers: 8/8 (This helps better encapsulate the flex material)
- Bed/Extruder Temps: 60C/205C, First Layer: 60C/215C
- See attached images for lowered FlexPLA print speeds
- Purge Volumes: 60/60 all filaments
Iteration, Iteration, Iteration... I started with a 28mm tabletop version of this chest I made a while ago. I always wanted to make a bigger version of this that could open. Plus, part of the reason I purchased my MMU2 was to play around with mixing in flexible materials. The E3D tool changer comp. seemed like a good reason to give it a go. I hope you like the results. Enjoy!
Lots of test prints!
Cross Section with some features of the model
Some interesting design elements:
- No support material needed!
- FlexPLA is locked in place in case of delamination with captured chamfers.
- Multi material nozzle size labels can be inserted into lid to keep track of which nozzle are placed where
- Print-in-place flexible hinges for lid latches
- Nozzle decal on chest lid
- I seperated the rivets into there own file so they could be printed in FlexPLA for a rubbery feel (MMU2 users beware). Or, use a fifth color for even more contrast.
*The chest can be "locked" by inserting 1.75mm filament through the latches
- If users don't have multi material capability it can be printed in a single color and will still operate.
Print Settings for FlexPLA
In Slic3r I copied the filament profile for SemiFlex or Flexfill 98A and changed the temps to standard PLA listed above, turned on cooling, and copied and pasted an MMU2 Compatible Printer Condition from another default MMU2 filament profile
FlexPLA Temps: Typical PLA temps
FlexPLA Cooling: On
FlexPLA Dependencies: Compatible Printer Condition copied from MMU2 filament profile
