Spacer for filament vaccum bags

prusaprinters

<p>I had some trouble placing and using the pump included in some filament vaccum bags (e.g. <a href="https://www.3djake.com/3djake/vacuum-set-including-pump">https://www.3djake.com/3djake/vacuum-set-including-pump</a> ).<br>When you use the pump to have to apply some pressure on the pump, so that it's sitting airtight on the vacuum bag, but that also means, that you are pressing the top layer of the bag onto the bottom layer of the bag, which reduces the airflow.<br><br>So I printed the spacers, which can be placed inside the vacuum bag and place the pump outside onto it. With the additional space between the two layers the airflow is better (Maybe you have to see the pictures, because my explanation is not the best :D).</p><p>It also possible to move the spacer afterwards, to close the valve as written in manual.</p><p>I created two version, one need less material but has more overhang, the other one has less overhang but needs more material.<br><br>I printed both version with Prusament PLA and no supports on a Prusa Mini+.</p>
