MakerChip Auto Swapper

Description
When participating in an event, you might want to exchange maker chips even if you leave your booth
For such occasions, I created a machine that exchanges maker chips unattended
There are also great predecessors, but this one uses a simple slide mechanism
25/9/26 Update: Updated to an improved version. Btm_pipe is now stable, and filament consumption for Slide has been reduced
■Parts
S_Plate: This is a core part that slides to exchange coins. It would be easy to understand if you change the color of the arrow part
M_Plate: This is a core part that slides to exchange coins. It can also be pushed back using a φ40mm rubber band
Top_Pipe: This is a cylinder for storing a large quantity of your own coins. You might want to customize it
Btm_Pipe: This is a cylinder where exchanged coins fall, and also the base of the main unit. You might want to customize it. It's not essential; in the photos, a commercially available transparent water bottle is used as a substitute instead
Slide: This is a slide where your coins fall while sliding. It's not essential for functionality but for fun. Since it uses a lot of material, you might want to customize it

■Assembly instructions (Video to be created separately) 25/11/29 Update
1. Insert S_Plate into the groove of M_Plate, press down with Top_Pipe, and fix it with screws
2. Attach the rubber band to M_Plate
3. Fix Btm_Pipe to M_Plate with screws
4. Fix Slide to M_Plate with screws
5. Attach lids to Top_Pipe and Btm_Pipe as needed
M_Plate has three sets of screw holes; Top_Pipe is fixed to the front side, and Btm_Pipe and Slide are fixed to the back side. It would be good to attach the rubber band to M_Plate as shown below:
