Aquarium Test Tube Holder

prusaprinters

<p>Tired of carefully balancing the test tubes while testing water parameters in my fish tanks, I designed this test tube holder with a slit in the back to slide a piece of paper or index card for a white backdrop to see the colors clearly.</p> <p>I recommend printing in grey, white, or black so as not contrast against the testing liquids.</p> <p>Holds 6 test tubes with lids on. Doesn't need supports, just print the bottom right side up, and the top upside down, then apply a bit of super glue to the slots on the sides.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>i3 MK2.5</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>200</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div> <p><strong>Filament:</strong> eSUN PLA+ grey</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Print the top upside down and the bottom right side up, then connect with super glue in the slots.</p></div> </p></p></p> Category: Biology
