Dustbin Latch for Dirt Devil M2724-6

For Dirt Devil M2724-6. We lost the part that broke off, so it may look a lot different. However, my design should be a lot more stable and is easy to print (and is much easier to replace if it breaks again).

Printing: Use suitable filament (ABS, ASA). PETG might work but is possibly too soft. Don't use PLA, it will become too brittle with age. Use 3 or more perimenter lines, increase infill (25% or more), supports on build plate only (to get better finish on the recessed screw hole).

Installation: You need an M30x40 screw and needle-nose pliers. It is not necessary or even helpful to disassemble the dustbin, as this does not improve accessibility at all. Remove the broken latch by drilling out its two plastic hinge pins with a 5 or 5.5 mm drill. It's a bit fiddly, but with both pins removed you can twist it out. Be careful not to shoot the spring around. If you lost the spring when your latch broke, you can disassemble the silver handle and use the identical one from the mechanism in the grip (will not work anyway with the printed replacement part). Put the replacement in position and slot in the spring (it goes in a recess on the dustbin side, and slides over a cone in the replacement part). It's a bit tricky, use the needle-nose pliers if necessary. Once the spring is in the part will stay in place. Put the screw through the printed pin with the recess for the screw head, and slide both through the frame and the latch part. Then insert the other printed pin from the opposite side. This has two flattened bits, grip these with the needle-nose pliers and fully fasten the screw (can take some force, there is no printed thread as the screw is supposed to lock in permanently).

Note: I lost the original part, so I cannot reproduce a safety feature built into the dustbin: You are not supposed to use the dustbin handle to carry around the vacuum. For this reason it has a spring-loaded mechanism built into the handle, that triggers the original latch when lifting it that way.  I.e. when you do this the dustbin will release instead, preventing you from lifting the vacuum. I think this was designed to prevent the vacuum from accidentally dropping when carried this way (the original load-bearing part of the latch is only 2 mm strong). With my replacement this safety feature will not work, if you want this you'll need to improve my design. I never carried the vacuum this way, so I didn't really care. I made the replacement as strong as I could, in theory it should now be able to support the weight of the vacuum, BUT THIS DEPENDS ON YOUR FILAMENT, PRINT SETTINGS AND PRINTER ! I take no responsibility for broken floors or feet or squashed pets etc.
