Seeed reTerminal E1003 spacer to fit IKEA RODALM picture frame

These spacers makes it easy to mount a Seeed reTerminal E1003 grayscale epaper device into an IKEA 21x30cm RÖDALM, centering the asymmetric device vertically. The device is sandwiched between the matte and the backing board. Please note: this is for the European version of the RÖDALM - other continents may have different dimensions and would not fit this adapter.

Print 2 sets of spacers, then flip one over to have the mirrored version.

You can use the stock matte that comes with the IKEA RÖDALM frame, but it's a bit too small so it covers a lot of the reTerminal's panel. Instead, I had a custom matte cut online that matched the exact dimensions of the visible area. I used a Dutch webshop but there are similar shops operating in every country.
