Expansion bar for e.g. door frame renovations

prusaprinters

<p>I smiled as the idea popped into my head :) And i have started to design.</p><p>After 3 try and error finally working project.</p><p>Expansion bar do not have length size limits, as it is <strong>extesible by water pipes 25mm diameter</strong>.</p><p>Tested for door frame change when the foam is drying.</p><p>I have tested also for supporting plasterboard on the ceiling with longer water pipes.</p><p>Water pipes visible on the photos. I use this design as it is really cheap. Water pipe 2-3 meters cost 1 euro ;-) Biggest cost is filament used.</p><p>The heads of the screws and stands are angled to hold the water pipe insertion.</p><h3><strong>Printing</strong></h3><p>Print without support.</p><p>Some modifiers are required so i have included 3mf files, helpfull also for orientation models on the printer. &nbsp;If you like to use longer water pipes increase infill of e.g. screw heads.</p><h3><strong>Parts</strong></h3><p>Complete printing parts are:</p><p>2 x stand</p><p>1 x left screw</p><p>1 x right screw</p><p>1 x double threaded pipe</p><p>&nbsp;</p><h4>UPDATES</h4><p>added one more forgotted file for stand in PETG</p><p>updated print time as it was previously sum of PLA and PETG ;-)</p>
