Hi!

This is a fully functional multi-material printable backpack - hard shell style.

I tried to make it a big as possible for my printer (which is Bambu Lab P1S). I apologize to A1 mini users but sadly this will be too big for you.

• The main parts are printed in PLA but PETG will do or any other material of this type.
• The straps, handle, nets etc. need to be with a flexible material, otherwise it simply will not work. I used Overture High Speed TPU 95A
• please adjust filament settings accordingly and make sure your print bed is clean and grease free as some parts (bolts for example) are very small, calibrated filament will give the best possible results :)
• if you'd like to make the print stronger increase amount of walls in the slicer
• 2 sizes of straps available, so mix and match to fit your needs/size
• I didn't have a banana for scale so I used an empty filament spool, hope it works too :)

Files included:

• 4 x 4MF files - main parts, bolts, locks and TPU parts
• STL file of every part included in this project
• Assembly Manual (.pdf)
• Screw Driver.3MF file (for the bolts)

Why print a backpack you might ask? For fun! Plus, lots of customization options.. you can spray paint it, draw/write on it (see photo), print it using the most awesome filament colors on the market, maybe a glow in the dark or transparent? I know I'd like to see that!

But wait, there's more... There are other variants of the backpack coming.. So far I plan on releasing one in the shape of a:

• cat
• ladybug
• panda (?) or a penguin.. or both?

Please let me know if you encounter any problems with the files or the model so I can fix it.

Selling, sharing or distributing any of the files is strictly prohibited. This is for personal use only.

This is a functional backpack yet still it is only 3D printed and should be threated as such. It will never be as strong as the ones bought in the stores :) something to keep in mind

Happy Printing! :)
