<p>Simple box with lid sized for a 77mm x 62mm x 6mm aluminum PTC heater element (e.g. <a href="https://www.aliexpress.com/item/1PCS-PTC-Thermostat-Aluminum-Heating-Element-Heater-Plate-60W-AC-DC-12V-180-Degree-Incubator-Dehumidification/32812440130.html">https://www.aliexpress.com/item/1PCS-PTC-Thermostat-Aluminum-Heating-Element-Heater-Plate-60W-AC-DC-12V-180-Degree-Incubator-Dehumidification/32812440130.html</a>)</p> <p>Since I needed to go above 60°C, I cast mine from concrete (and printed the strain relief with XT). Files for the mold are included (I only needed one so I printed it from PLA as a single use mold).<br/> If you want to use the cable guide, you need to put a 40x20x10mm spacer into the inner part of the mold (I used a block of Teflon). M3 nuts, M3 screws and small zipties are needed for the strain relief. Drill a 3mm hole through the base to attach the relief to the box with an M3 screw.</p> <p>I designed two vial holders for this: <a href="https://www.thingiverse.com/thing:2891050">https://www.thingiverse.com/thing:2891050</a></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Ultimaker</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ultimaker 2</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.2</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div></p> </p></p></p> Category: Tools
