Can Crusher (12oz., 16oz., 20oz.)

Version 2.0 Update

• Significant reductions to time and filament required
• Increased wall count for improved durability 
• Added internal walls to boost overall structural strength
• Changed print orientation so the model now requires NO SUPPORTS!
• Remodeled geometry to improve layer direction relative to applied forces
• For PETG prints: ensure the part cooling fan is turned off
• Glue stick was used on the print bed for better adhesion during testing
• Plunger component remains unchanged

Wanted to make this soda crusher since only models I could find required additional hardware, or would have sharp edges where you would place your hands when operating. I believe this solution works pretty well, and I'm satisfied with how it works at home.

This works with cans from 12oz standard soda cans, up to 20oz Redbull cans (I'm not a Monster drinker but should fit just fine). 20oz cans will extend above the top of the base but should compress just the same. Standard size soda cans compress to about 40mm, 20oz cans compress to about 55mm. This can even be used to crush 20oz soda bottles.

Base is best printed in PETG. I printed mine in Bambu Labs PETG‑HF. Plunger can be printed in PLA.

It is highly recommended to squeeze a dent into the can prior to crushing. This will significantly reduce the amount of pressure needed to operate this crusher.

Holes on the sides allow finger ejection in case the can gets stuck at the exit; however, there should be more than enough clearance for even the 20oz cans to slide right out.  Vent holes are on the side of Plunger are to prevent air from getting trapped in the hollow center.
