I've got several requests to adapt my design of the clip for the larger 45/65l boxes ( Never lost Ikea Samla Clip (45l + 65l)) to the smaller boxes 5l/11l/22l. So far I didn't use the smaller boxes as dry boxes and until recently even had one.
I tested other hinged clips but wasn't satisfied with the stability of the hinges, which broke after clipping them to the box in my case. So I started to downsize my clip for 45l/65l boxes, with the main goal to keep the strength of the hinge even for the smaller design.
What I recognized when stapling large and small boxes was, that the design of the 45l/65l clips didn't allow to staple a 11l box onto a 45l/65l box due to the grip line on the end of the larger's clip arm. So I decided to switch to a 'T'-like design to get a better grip for mounting and unmounting the clips, while leaving more space for the larger base floor of the 11l box when sitting on the lid of a 45l/65l box.
Here you see a 11l box sitting on a 22l box sitting on a 65l box.
The whole clip design is very similar to the original 45l/65l design. In fact, I started with 75% of the size. Doing so brought down the overall size and almost fitted to the smaller box rails, and – more importantly – still left the functionality of the hinges as inplace-print intact. Then the arm parts of the clip needed some resizing and multiple iterations.
Please forgive any misfits of the clips. I recognized at least some differing details of the Ikea Samla boxes and lids if pruchased at different dates or locations.
The clip is designed for a thickness of 3mm of the sealing foam. I used this one Ratel Black Rubber Weatherstrip Foam : Amazon.de: DIY & Tools which is 6mmx3mm. I propose to glue the strip onto the box because you can exactly position it to the flat area that makes up the contact area between box and lid. Finding the right position when trying to glue it to the lid may be more difficult.
Glueing the clip to the box depends on the type of glue you are using. I made best experience with a glue typically used for PVC (Tangit PVC-U Plus). After some sanding of the perfect box plastic surface, this glue works very well for me.
If you don't like the glue, you can also use a thin(!) double-side tape to fix the clips to the box.
Use 4 (all on the long sides) or 6 (4 on the short sides and 2 in the middle of the long sides) clips for one box.
Important: Print the clip in a vertical position, so that the clip has the strongest structure along the clipping direction.
Print w/o supports. I propose a brim when printing in PLA. Printing with PET-G w/o a brim worked for me.
Use 3 contours for outer walls, so that the complete arm of the clip gets solid.
6 clips for 1 box need approx. 38g filament and print in 4,5h.
