prusaprinters

<p>This is a little complex design developed for the <a href="https://www.prusaprinters.org/prints/25857">Prusa Face Shield</a> where, sometimes, the rubber band is difficult to found.<br/> This adjustable headband is a part and originally intended for a helmet in a project where I worked on its development inside hackability association.<br/> For some intresting project you can visit <a href="https://space.hackability.it/">space.hackability.it</a> and for more info about this non profit association visit <a href="http://www.hackability.it/">hackability.it</a>.</p> <h3>Print instructions</h3><p>Just you need PETG and PLA</p> <p>For the two bands i use only the PLA, but i think PETG work as well, maybe better, 0.2 layer height, 4 perimeters and 100% infill.</p> <p>The internal_gear must be printed with PLA because the design not work with PETG, i printed it with 0.2 layer height and 100% infill.</p> <p>In the part_1 set the support from the bed and add some renforcement for the two slots, i printed it with PLA, 0.2/0.07 variable layer height and 20% infill; to take over the supports you have to use a cutter and a screwdriver (look at the pictures), you have to be careful.</p> <p>Fot the part_2 i use the PETG because sometimes the join break apart with the PLA, i printed it with 0.2 layer height and 15% infill.</p> <p>To insert the bands in the part_1 you can use a screwdriver (look at the pictures), but be careful to not break them (i know it's a little difficult but the design it's developed to avoid them getting stuck in it); and to insert them in the prusa face shield use a little force, them are designed to remain stuck on it!</p>
