Free 3D Printer Accessories STL Download - SV08 riser with closeable ventsby GizmoTheRogue

This is the first time I've made something this precise. I'm genuinely shocked it worked. Your milage may vary.tested prints for a few hours with vents open and the glass top on. Never went over 35C in the chamber. Didn't try to turn the exhaust fan on, not sure if that would help. probably would. But I didn't have any problems printing PLA or PETG on 2.5 hour prints back to back. Again, your milage may vary.I like the height added to it. If you want it shorter just uncheck "uniform sizing" in the slicer and lower the Z height. ALSO- you can't use the stock spool holder with this. I made do and cut out part of it with a rotary tool because I didn't have another place to put my rolls yet. you could probably get away doing that with snips and some strength.
