BIG Reusable Spool for Paramount et al

prusaprinters

<p>Aggressively rejiggered a Thingiverse reusable spool design to make it accept the Paramount refills that are something like 70mm wide and 100mm diameter (at the spool). For it to work for me it had to stay within ~85mm total width so it will fit in my Sunlu dryer boxes (S1).</p><p>In an effort to keep it somewhat universal to accept any future refills, I kept the center bore small and designed a drop-in bushing that fits the big diameter Paramount rolls perfectly. The thinking is, if I end up with any other odd-ball refill spools I should be able to quickly mix up a different bushing to fit and keep everything rolling nicely inside the Sunlu boxes. If you had an even wider spool pop up, the threads tolerate that out to a spool width of maybe 85mm or so, and you'd just lock them down against a wider bushing.</p><p>Also, I revised the center bore diameter to accept the rolling desiccant cages I use inside the Sunlu boxes (see my prints).</p>
