RISER PYRAMiD CREALITY K1 MAX

I'm publishing it at your request, but that wasn't my goal. Don't expect a super-finished product; it was solely for my use.

Choose a heat-resistant filament like ASA or ABS, avoid PLA.
I chose to weld the transparent synthetic polystyrene (STYREX) glass panes to the structure I printed in ASA with acetone glue (for PVC). Make sure the glue is compatible with the materials used.
The glass are cut with a cutter. Make a clean and sufficiently deep cut using a ruler, protecting your fingers. Place the part to be preserved between two boards and bend hard to break.

You can also download the M10 Bowden adapter, which makes it easy to remove the PTFE tube. It's sturdy and securely anchored to the extruder.
