Technical Tips for 3D Printing

Materials : PETG recommended, otherwise ABS, ASA, Nylon depending on use or other technical materials. PLA not recommended
Orientation: preferably flat, with easy-to-remove stand
Support: Adapt angle to avoid inserting a support inside the fittings that would be impossible to remove, given the inside diameter.

The models shown in the photos and/or GIFs (printed from the STL files you are about to download) have been deliberately printed from the test phases on an original ENDER 3 PRO, simply equipped:

a BLTouch,
and a PEI plate.

🎯 Objective: to prove two essential points

3D PRINTABILITY These models print perfectly in FDM.
They can be printed on all FDM 3D printers, without the need for a high-end or state-of-the-art machine.

👉 If printing is excellent on an Ender 3, it will be just as good on your printer.
