Oversized Playmat Adapter for Vinyl Roll Holder

I have several large playmats that roll up to about 80mm diameter (Inked Gaming Mousepad XXL 48" wide matts) and I wanted to store them in this door hanging Vinyl Roll Holder I got which fits most of my board game playmats. This is a simple adapter that allowed me to do that. Link below for the holder I bought, but I'd bet a lot of them are similar. The total width for this is 180mm.

It does require some kind of clip to support the other side. Included in this design is a screw to fasten and the tolerance on this is tight so you'd likely not want to move it around after clipped in. An alternative are binder clips which you can find an example below).

No support required if printed up right as in the rendered picture

Roll Holder I used, but others may work just as well

Binder Clips (in case you want to move around easier than the screw allows)
