A drawer that attaches under the wallet with 5mm of usable height, enough for 2 layers of coins or other stuff like keys and paper money. It is designed to simply snap or slide onto the wallet, an optional band can be used to hold it more securely. You may need to sand the wallet down a bit if the fit is too tight. Printed with the big face down and 0.2mm layer height.
The author remixed this model.
A drawer that can be used together with the original wallet.
