Modular Organizer Drawers (Plus Size)

Andre Campos' drawers are the best I could find for my needs. I've tried a number of models  and was always disappointed in terms of space and stability, but his design is much better. 
 
Simply scaling beyond a certain percentage leads to problems because of scaled tolerances of drawers and connectors. In order to meet my size requirements, I enlarged the drawers by 4 cm in width and depth and by 2 cm in height. This enlarged version is of course also suitable for further upscaling in the slicer and can be used for drawers of 20 cm (125%, see photos) and even significantly larger. The stability of the original model is absolutely suitable for such sizes.

I optimized the geometry of some of the models and added new drawers (1x2, 2x3, 3x2 and 4x4) and variants with an inverted handle (for dusty environments).

Dimensions:

Print the drawers with their bottom flat on the bed. I always print a tiny tree support under the handle. The 2-way, 3-way and 4-way connectors should be printed standing upright on the bed. Make sure they stand on the flat end and use a small brim. The corner pieces can be printed flat on the bed.

I recommend a 0.4mm nozzle and layer height of 0.2 mm (perhaps 0.3mm with a 0.6mm nozzle works well on your printer too). I printed my drawers at 125%. I used 2 perimeters and 5% infill. That results in sturdy drawers and shell - for larger drawers or heavier loads, I recommend using more infill, and if you want to go > 140%, even more infill and 3+ perimeters.

For each connection of an edge, 2 connectors are required.

The drawers in the “Handle 1” and “Handle 2” folders differ in - the handle ;)

You can control the strength of the bottom of the drawers by the number of bottom and top layers. I printed the larger drawers with 3 bottom layers and - for optical reasons, to cover the infill as well as possible - with 4 top layers. If the quality of the top layer of the bottom of the drawer is not an important criterion for you, you can of course only print 3 top layers. Again, for larger drawers or heavier loads, you may want to add a perimeter/layer.
