Espresso Cup Protector

Want to enjoy your espresso in style while hiking or camping? This design utilizes the soft TPU 85A filament to create a cushion that can help protect your porcelain cup while you're traveling. As can be seen in the GIF attached to this post - I tested the design by throwing it at rocks and logs - not that I would recommend being that rough!

Device Options

Although only one print profile is included, this project is flexible to be printed on a variety of devices.

H2D Laser

• The .lac file for cutting the leatherette and etching with the laser is available in this profile.
• Dual-color along the Z axis works well with the H2D but would be wasteful with single-nozzle printers.

All other devices

• Printable on all models including A1 Mini
• There's an optional TPU strap that can be used if you don't have access to a laser cutter. 
• Colors can be reassigned in Bambu Studio or handy for single-nozzle printers.

Parts

1. Strap (leatherette or 3D printed)
2. Cover (H2D Laser version only)
3. Rim (H2D Laser version only)
4. Lid
5. Case
6. TPU Handle
7. TPU Lid
8. TPU Base

Assembly Instructions

	Place the TPU base into the base. Because of the rubbery nature of the TPU, glue should not be needed but can be used if you'd like.
	Pres the TPU lid into the lid - leave the open area pointing out.
	Place the TPU handle into the lid. The beveled portion should be oriented towards the back.
	H2D Laser version only: Apply a small amount of glue to the top of the lid.
	H2D Laser version only: Place the cover graphic
	H2D Laser version only: apply glue to the outer rim between the graphic and the lip.
	H2D Laser version only: Place the rim onto the lid and press it until it dries.
	Attach the strap by feeding it through the gap in the handle and then over the peg.
	Pull the strap across the top of the lid to hold it secure. Then, press the hole on the strap over the nub to hold it in place.

Printing Tips & Project Notes

• I have only tested the interior cushion with TPU 85A and recommend following the wiki carefully for this process.
• The included print profile utilizes the dual nozzles of the H2D for multi-color along the Z axis but this can easily be reassigned to a single color in Bambu Studio or Handy.
• Smooth PEI plate recommended for the most consistent surface quality.
• AI usage: although I create illustrations and sourced images for the card, I used an AI process to apply the woodcut effect. After that step, I locally created and cleaned up the vectors that are used for the cards.

I love creating models to share for free, personal use. If you enjoyed this model, please consider buying me a coffee or joining me on Patreon.
