Bagopener - Plastic Bag Opener

prusaprinters

<p>This is a gadget for opening those very thin plastic bags (like cheap plastic trash bags) that always seem to be glued shut and are very annoying to get open.</p> <p>To use it you need add two pieces of adhesive tape (variously known as Scotch tape, cello tape, sello tape, etc.) - width should be 3/4"/20mm. To add the tape take a strip about 1-1/2" (40mm) long and insert one end in the slot on the cylindrical part. Stick a short bit of tape to one side of the cylinder and then wrap it in the reverse direction STICKY-SIDE-OUT around the cylinder so that it sticks to itself. The idea is to create a "sticky cylinder." Do this for both cylindrical parts.</p> <p>In use, simply hold the bagopener as shown in the photo, and pinch the two sticky cylinders on either side of the annoying bag - let it spring open and it will pull the bag open.</p> <p>The OnShape 3D CAD files for this can be found here:</p> <p><a href="https://cad.onshape.com/documents/067e97f91baf8f462dd8bdbd/w/7cc4eb6873708067af683a49/e/658faf1093271a111480512b">https://cad.onshape.com/documents/067e97f91baf8f462dd8bdbd/w/7cc4eb6873708067af683a49/e/658faf1093271a111480512b</a></p> <h3>Print instructions</h3><p>Print in PLA - use the provided 3mf file; otherewise</p> <ul> <li>.3mm layer height</li> <li>10% rectilinear infill</li> </ul>
