<p>This is a filament buffer and spool within an 'Ikea drybox 365+ 10.6 liter' for the MMU2s.</p> <p>I wanted my filament-spool, but also the whole route to my MMU2, in a dry and protected environment. So I designed a buffer within the largest drybox of ikea:<br/> <a href="https://www.ikea.com/nl/nl/p/ikea-365-voorraadpot-met-deksel-rechthoekig-kunststof-s79276760/">https://www.ikea.com/nl/nl/p/ikea-365-voorraadpot-met-deksel-rechthoekig-kunststof-s79276760/</a></p> <p>Required:<br/> -4x Iglidur bearings GSM-1012-10 or similar. (<a href="https://www.igus.eu/product/1">https://www.igus.eu/product/1</a>)<br/> -7x M4x20mm tapered bolds and M4x2mm nuts<br/> -grinding paper for the printed safts.<br/> -double sided tape to mount the buffer in the ikea box.<br/> -I used the PC4-M10 tube connector. Drill a hole of 9 mm in the ikea box and screw it in.

(I will change this in version 2) </li> <li>use grinding paper for the two printed axis.</li> <li>I drilled the output hole with 4mm, as the PFT tube needed to be slided more inwards. (See picture).
