Hex Pattern Coasters With Drip Ring

prusaprinters

<p>These are coasters designed to print with two color changes. Print in all PETG, or layer TPU-PETG-TPU, with filament changes at 2.5mm and 4mm. A 3MF project file for PrusaSlicer is included which has everything set up properly.</p> <p>Note: the Hex2 design has removable supports built into the STL. With all of the designs, be sure the solid infill on the first solid layer goes across the underlying pattern, not parallel to it with long un-supported stretches.</p> <p>If you combine TPU and PETG, the print settings required are rather different. I generate gcode for TPU and PETG separately, then use <a href="https://github.com/joshcarter/gcode_splice">this gcode splicing tool I made</a> to combine them. I've tried other combinations of materials (PLA, ABS, etc.) but had trouble with adhesion between materials. TPU (also TPE) and PETG stick together very well. If you use Overture brand TPU, I've found that I need to print that hotter, around 245C or 250C. Other brands of TPU print well at 230C.</p> <p>Disclaimer: the Hex1 design is similar to another model on Thingiverse which has a "no derivatives" license. I asked the designer to allow me to post a remix but never heard back. Mine is clearly inspired by that one, but I modeled mine from scratch and added substantive changes, so I feel justified in posting my model. I'm not making any money from this; I'm just posting stuff I've made that I hope others find useful.</p> Category: Kitchen & Dining
