Customizable Spacer

thingiverse

I have designed an upgraded Prusa i3 Hephestos spool holder featuring a 32mm installation tube. I employ this expansion tube to keep the filament spools separated, so they cannot come into contact with each other during printing. You can effortlessly create your own expansion tube using the Customizer. The Customizer generates one STL file for the expansion tube and an additional text-only file if you want to utilize dual extrusion. Don't forget to include some backlash in the inner diameter when customizing, otherwise the expansion tube will be too snug. In the first image, the expansion tube is colored according to the electronic color code. Instructions: If you desire to print text on the expansion tube, please note that there is sufficient space on both sides. Otherwise, leave the text fields blank. I printed my expansion tube with 20% infill and a layer thickness of 0.3 mm.
