Desiccant Container for Spool Center Hole

prusaprinters

<p>I suggest using the gcode or 3mf over the STLs as there are many setting changed to achieve ventilation.</p><p>This uses exposed infill for ventilation and faster print times than modeled holes. The STLs have no air holes modeled. 25 % gyoid infill, zero perimeters on the can provides ventilation. Optionally, cylinder modifiers can be added modifiers can be added with 40 % honeycomb infill to provide ventilation to the top and bottom.</p><p>The lid is a snap fit, may require adjustment of scaling. The provided 3mf and gcode have the lid scale factor set to 99.9% which results in a nice fit in generic PLA on the Prusa Mini. I printed a bunch of these at high speeds on a Voron 0.1 with an 0.6 mm nozzle and found 99.7% was better in that case.</p><p>This should work with either silica gel or molecular sieve desiccant in larger balls. What I'm using is approximately 3 mm balls. Remove the desiccant for drying. Avoid the color indicating desiccant varieties as the cobalt chloride indicator is toxic. It is probably best to leave some air space in the bag to allow circulation.</p>
