Improved All-In-One Temperature and Bridging Tower -- Hi to Lo Temps, PLA/PETG/ASA/TPU/PCCF

Remix of Tronnic's bridging tower, with the temperatures from highest on the bottom to lowest on the top. This way, you shouldn't experience clogging issues if the lowest temperature is not enough to properly melt the filament.

Many pre-sliced gcode files are provided, as well as 3MF files for re-sclicing, plus STL and STEP files. 

UPDATE 8/6/2026: Added support for INDX

Interested in a smaller model? A different filament type? A printer type not on the list? A different nozzle size? Check out my fully customizable temp tower at https://www.printables.com/model/216967

Currently supported printers: 

• CORE One INDX 8T and 4T HF (pre-sliced files are for extruder 1)

• CORE One L (HF)

• CORE One (+) (HF)

• Mk4(S) (HF)

• XL (pre-sliced files are for extruder 1)

• Mk3.5(S)

• Mk3.9(S) (HF)

• Other systems such as Mini, Mk3S, etc, see the Legacy Printer folder—all those files should work but will not be updated going forward.

Currently supported materials:

• PLA

• PETG

• TPU

• ASA

• PCCF

Version History

UPDATE 5/8/2026: Resliced for CORE One L with updated start gcode.CORE

UPDATE 2/2/2026: Added support for CORE One L.

UPDATE 2/02/2025: Added support for Prusa CORE One.

UPDATE 1/15/2025: Fixed error with the protrusion on the backside. Fixed gcode to adjust for being off 1 layer for some models. Resliced for new versions of print/filament/printer settings.

UPDATE 11/10/2024: Major refresh:

• Temperature range for PLA temp tower was changed as Prusaslicer now uses a higher temperature.

• Added a temp tower for PCCF.

• Created new temp tower configurations for Mk3.5(S), Mk3.9(S), and Mk4S. including versions for high flow nozzle.

• Changed ABS to ASA—ASA is just so much better, friends shouldn't let friends use ABS...

• I no longer support 0.6mm nozzles. The new machines make it so easy to swap nozzles back to a 0.4mm nozzle to run the model, or use my customizable temp tower script (see above) to create your own temp tower.

UPDATE 9/25/23: Re-sliced and re-uploaded models for Mk3S+, to work around a bug in PrusaSlicer 2.6.1 (per @WilliamKapla_446980). 

UPDATE 6/16/23: Versions for Mk4 and XL

UPDATE 3/22/22: Temp towers for TPU added.

UPDATE 9/21/21: Temp towers for ABS/ASA added. The GCODE is for ABS. For ASA, please use the 3MF file for ABS, select Prusament ASA from the Filament Settings dropdown, and reslice. The tower will still say “ABS” but the temperature ranges are appropriate for ASA.

UPDATE 2/3/21: Messed up the profiles for the 0.6mm nozzles in PETG. Should be fixed now.

UPDATE 12/27/20: There was an interest in models for printers with 0.6 mm nozzles, so I added those .3mf and .gcode files. I also added files for the Prusa Mini.

Print instructions

Use the provided GCODE files or reslice the 3mf files.
