prusaprinters

<p>The stock plunger did not press evenly on the cartridge plunger leading to enormous leakage at the back of the cartridge.&nbsp;</p><p>I almost exclusively use the polymere cartridges from Würth (German professional hardware store)</p><p>I used a metal washer inside of the part to distribute the load of the push road. Add a pause in the gcode to insert said washer.&nbsp;</p><p>Use plenty of infill and shells.</p>
