A Refreshed Version of the Bambu Lab - Tools and Accessories Box

After the tremendous success of the original Bambu Lab - Tools and Accessories Box , which garnered thousands of downloads and makes, I decided it was time to refresh and enhance this project. This updated version introduces significant improvements across almost every aspect while maintaining the core functionality that made the original so popular.

And here is the new version for comparation and without any accessories or tools.

Important considerations before start

First of all, I would like to congratulate Prusa for adding the multiple build plates feature. It was truly something that was missing. At the time of the project launch, this feature is still in beta, but it works very well, so feel free to use it. It is a mandatory requirement to open this document in Prusa Slicer. However, if you are not willing to install this version, I am also providing the pre-sliced versions.

Another characteristic of this project is that it is only available for printers with the MMU, due to the use of multiple colors, but especially because I am using a “special” technique that allows for very easy support removal with a near-perfect finish in the areas where supports are applied. More information on this will be provided later

Storage Capacity

This version of the case allows you to store:

First Half of the Case

- 1x Kit of Hexagonal Keys , along with a nozzle unclogging needle in the same compartment. - 1x Pliers (I used this one , it seems commonly available) - Various pockets with Lid, and pockets for bolts and other small items Second Half of the Case

- 4x Nozzles - 3x Silicone Socks - 2x Complete Nextruder hotend , including fan, cables, and silicone sock. - 1x Nozzle remover with torque limitation - 1x Small pocket with lid for small items related to the hotend Key Improvements

New Design, more actual

The new version features a more modern aesthetic, though I understand design preferences can vary. The updated look aims to balance form and function while staying true to the original concept.

Enhanced Dimensional and Geometric Precision

The modules now benefit from the advanced dimensional and geometric precision I developed in my most recent project:

UMSS - Universal Modular Storage System

Almost all modules, can be found here

UMSS - Prusa Tools and Accessories

UMSS - For Prusa Mk4 Spare Parts

This project builds on its predecessor:

- MMSS - Multi-Modular Storage System Magnetic Closure System

The closing mechanism has been upgraded to a magnetic system, inspired by my previous projects. This makes the case more user-friendly and provides a reliable, sleek solution compared to the earlier version.

Monobloc Structure

Unlike the original Tools and Accessories Box , this new case features an almost monobloc structure. This design choice addresses structural issues from the earlier version, improving durability and simplifying assembly.

Design Challenges: The Handle

One of the most complex aspects of this update was the handle. My goal was to integrate it seamlessly into the body of the case.

For this version, I redesigned the handle, choosing to keep it attached to the main body rather than making it a detachable piece, as I did in the MMSS case ( link here ). While a detachable handle might have simplified some aspects, it would have disrupted the clean, cohesive design I envisioned.

The Trade-Off

The main challenge with the handle was the support material required during printing. Adjusting the model’s orientation to reduce support material was partially feasible but would have compromised the areas for the magnets. This trade-off was a deliberate decision to balance design, functionality, and printability.

Flexibility Through Modularity

For users seeking more flexibility—whether they find the number of hotend pockets excessive or insufficient—the UMSS and MMSS projects offer an ideal solution. Both systems are fully modular, allowing for personalized configurations to suit a variety of needs.

Printing

A configured file is available for download. This file has multiple buildplates (Prusa Slicer 2.9.0)

One possible way to solve the issue of marks left by the supports required to print the suitcase handle is to use materials in the interface zone that are incompatible, such as PETG for PLA and vice versa. In this case, a PETG model with a PLA interface layer works well, as long as matte PLA is not used—in that case, the results are disastrous. That said, there are many PLA and PETG variations, and the differences between them can be significant. Test with a small part or use the "cut" tool to section the piece and print a portion of the handle. Observe the results—if they turn out well, you can try printing the entire piece.

Here are some guidelines, and no more than that, starting with "Print Settings":

In addition to the usual settings, such as enabling supports, you can adjust the following:

- Top Contact Z Distance : Set to 0.1 mm or even 0 mm. - Interface Pattern : Rectilinear (this seems to create a more uniform base). - Interface Spacing : 0 mm. Then, under Speed :
