"Can Handy" Storage Device

prusaprinters

The “Can Handy” is designed to give as much storage as possible, using as little filament as possible because my daughter (Gretta2.0) keeps bugging me about how much plastic I'm using.I've tested the design with several types of old UK food cans and developed two variants of the design:Ring-pull type cans (DV1-CANHDY-01.XX)low-profile tuna tins (without ring-pull) (DV1-CANHDY-02.XX)Note that all my cans are of the “ring-pull” type and I don't use a can opener on them. The clamp should still work on this type of can though as it clamps on the outside ring.Each variant has the following common features:A “Can Handy” clamp to attach to the top of an old canThis includes an internal lip to protect against sharp edges in the can.A lid with integral slot to suit a 9mm DYMO label.A wall mount for 5mm self-tapping screws.The files are developed in Fusion and I've attached the model files so that you can customise them to work with other types of can if necessary. Unfortunately Prusa doesn't allow .f3z file uploads and extracts them out into the constituent .f3d parts without the meta-data. Hopefully you will be able to get them to work anyway.Each .gcode file is for a different can variant and includes the “Can Handy” clamp, a lid and a wall mount.Printing:I printed these on a Prusa i3 Mk3S+ and use PETG as it has more spring in it for the clips on the lid.I used the textured bed, which gives a really nice finish - especially on the lids.You should note the print orientations in the supplied .3mf files - “Z” is reversed from the CAD model in some cases:No supports are necessary (Integral supports are included in the clamp design - no post-processing needed).Make sure the lid is printed “top face” downwards.Make sure the wall mount is printed “top face” upwards (it has an extra cut out in it).Make sure the can handy is printed "top face" downwards.I generally complete the first couple of layers at 100% speed and then wind it up to 200% for the rest of the print. This results in a fair amount of stringing with some filaments though so I have left the g code as standard Prusa speed settings.Updated:19/02/2021 - DV1-CANHDY-01.03.02 - Updated from 01.03.01 to fix a tolerance issue in the mounting design.19/02/2021 - DV1-CANHDY-01.03.03 - Updated from 01.03.02 to fix a split in the mounting design and increase the access hole diameter.19/02/2021 - DV1-CANHDY-02.03.02 - Updated from 02.03.01 to increase the access hole to allow for larger screws.20/02/2021 - DV1-CANHDY-01.02.02 - Updated from 01.02.01 to increase the diameter slightly and increase compatibility with more cans.
