Alcol Swab Dispenser
This is essentially the same model of the original condom holder just scaled down to 82%, so that it now comfortably holds 8 Kroger (and I'm sure other brands as well) isopropyl antiseptic wipes. Perfect to attach to your bot by whatever means you'd like for cleaning the bed between prints.
On an aside I printed this with clear t-glase at a 0.25mm layer height, and boy is it clear, the walls are nearly 2mm thick and I can still read the print on the packaging!
