Prusa i3 lack enclosure stabilizer
thingiverse
*NOW INCLUDES MINI VERSION* You should be able to mix and match the large and small pieces as needed, depending on your clearance between the top of the printer frame and your enclosure ceiling. The mini version includes 2 different sized nut's, 12mm and 14mm. I designed this telescoping stabilizer in attempt to make my printer more rigid without permanent modification or bolting it to my enclosure. The top piece is right hand thread, and the bottom is left hand thread. To install, thread both pieces all the way in, set on top of printer, and hold upper piece while spinning the middle nut. Long version - 85mm fully retracted 125mm fully extended (1 thread left) Mini version - (with 12mm nut) 28.25mm fully retracted 36.6mm fully extended (1 thread left) I recommend printing with something high strength like PETG or ABS. Mine was printed with Inland PETG.
