About this model

The integrated heater bleed key and a collection container makes bleeding your heaters super easy. No support needed. Note: If your wrench-key is to tight for your heater, you can find a slightly larger one in the download section. Please remember that you are printing plastic here, the outer and inner dimensions specify the exact material thickness. For me it works with PLA printed keys without any problems on every heater, if it breaks, then you can try it with stronger materials like PLA+, PETG; PLA-CF or try the new Bitholder version. To be absolutely sure, combine the container with a metal key. Good luck :) You can see the difference between the two key versions here: Standard key 5,0-5,1mmSlightly bigger 5.2mm Testversion: Bitholder (Red one) Try this if others dont work.
