This project is a small gift exchange table made to be used at festivals and small events where gifting is a core value. The goal of this is to allow people to exchange small items (such as trinkets, mugs, jewelry, etc.) similar to a Little Free Library.
Take a gift. Leave a gift.
Our exchange table has interactive LEDs, sensors, and turntable to provide an engaging experience for the user. The table spins for a randomized amount of time so you never know which gift you will get--will it be a happy surprise? ,':)
The table can hold up to 8 gifts at a time, and it can be powered with a generator for use at events where electricity may not be available.

The turn table is the part of this device that holds the gift and rotates. All files that need to be cut can be found in the Laser-Cutting-Files folder.
- (x1) 3/16" - 24x24" Plywood Sheet
- (x3) 1/8" - 12x12" Plywood Sheets
- (x4) 1/2" - 1.5x1.5" Wood blocks
- (x4) 3/4" Wooden balls (or any material)
- (x1) 3/4" - 1x1.75" Aluminum Block
- (x1) M4 - 20mm Screw (Set screw for motor)
- (x4) M5 - 25mm Screws (Secure aluminum block to table top)
- Wood Glue
Table_Bottom.ai
- (rectangles) Slots for securing dividers
- (x4 circles) Through holes to secure aluminum block
Table_Dividers.ai
- No holes
The aluminum block was created with a drill press by creating 5 holes on the front side using a 1/4" drill bit.
From there, from the top side, I then created a hole going to the center hold where the motor shaft would go to using a 5/32" drill bit, and then used a tap and die set to tap on a M4 threading into the hole.

To use, first place your gift you're giving away in an empty slot. Then wave your hand in between the IR Sensors to spin the table.
