4x6" Postcard Dispenser & Vending Machine

Description

The SKPOP 4x6" Postcard Dispenser is the largest variant of the k-pop photocard vending machine. The dispenser is best used a “lucky draw” machine for sticker sheets, postcards, or photo prints! 

• Works for cards up to 159mm in length and up to 107mm in width
• Holds a card stack of up to ~1.5" / 40mm in height
• Given the dynamic surface textures of postcards, it is best to use sleeves to ensure low and consistent friction between cards, which helps with dispensing. Gloss finish postcards without sleeves were tested to be compatible as shown in the gif
• Note: the handle one-way clutch tolerance is calibrated to X1C. A reduced tolerance version is available if your handle gets stuck. See attached step file.
