A cap for the reMarkable Marker/Marker Plus. It has a flat side to allow the marker to continue to sit flush and flat against the tablet magnetically. The cap can help prevent your pen nib collar from breaking, which is costly to replace.
Very simple to print- orient the flat side against the bed, with the open end for the marker standing up.
If you found this page via a friend, but don't have a printer, I sell them on Etsy for those without a printer.
The author marked this model as their own original creation.
