Door Brace for the (Un)original Prusa Drybox

When two (Un)original Prusa Drybox' are stacked, there's no way to hold the door open on the lower one. This isn't an issue with the default design but becomes an issue with the 5 spool rewinder remix installed because inserting and removing the filament is a two-handed ordeal. It's also nice to have the door propped open when feeding the filament to the MMU3. I'm not good at designing things, but I couldn't find anything to solve my problem. So, I fired up Tinkercad..because that's the only thing I know how to use. Assembly should be pretty straight forward. The TPU part is simply glued onto the arm. (Use very little glue to avoid squishing it out the sides) It uses M3 screws. I used M3 x 16 socket head for mounting to the drybox, and I think I used M3 x 12 for mounting the arm to the bracket. All holes are countersunk to allow socket head screws to sit flush. (This was not fixed in the photos, but has been fixed and tested before uploading) My bracket and Brace are both printed with PETG Prusament Jet Black. The Cushion is printed with TPU SainSmart Black.
