Qbrick Pro - Custom tool box mod for taller tools (up to 25cm tall)

Story time

I'm using Qbrick Pro system to hold all of my tools and stuff in my workshop. I was slightly annoyed that Pro system doesn't have anything higher than Toolbox (except Cart which is annoying to put on a shelf). Toolbox can accept things up to 19cm tall, while my plunge saw is around 24,5cm.

There's an option to use Pro Box 130 with extensions and a handle, but this is open box so not ideal.

If you had idea like me to put Technician case on top of a Box 130 and cut down bottom part of a technician case, you will quickly find out that this leaves a huge gap on the front and and a small one on the rear.

This project contains all the parts that will bridge those gaps and make Box 130 and Technician case into a single big container with a closing lid :)

Toolbox vs Technician case

This works only with Technician case (the smaller box with a lid), it won't fit Toolbox without modifications. I did a test fit and it seems rear and side parts (clips) will work out of the box, but for the front parts - gap is much narrower, so they will need remodeling.

Required parts

Prints

You will need to print all 6 models, 1 piece each except clip.stl which you need two of.

I printed all of my parts from PETG on Bear Prusa MK3 with 0.6mm nozzle.

I printed front, clip and drilling helpers at 0.32mm structural profile with 5 perimeters. For rear parts I used 0.15mm structural profile as at 0.32 stair-casing was too bad.

All prints were done with 25% infill. I used no supports, except for front elements - see the screenshot below.

Nuts and bolts

For assembly you will need:

• 26x M4 nylock nuts
• 12x M4 12mm screws, button head (e.g. DIN 7380)
• 2x M4 12mm screws, flat head (e.g. DIN 965, 7991)
• 12x M4 8mm screws, flat head

Tools

From required tools - appropriate screwdriver, drill with 4mm bit and something to cut out bottom part of Technician case. I did that with a Jig Saw.

Assembly instructions

This is the order in which I assembled my box.

Please note to align both cases in the same orientation. Front is where Qbrick logo sticker is located.

1. Print all parts.
2. Put front and rear elements into notches of 130 box. Push them down to they sit flush.
3. Put Technician case on top of 130 Box and see if everything lines up. You should be able to close original connector clips and front/rear parts shall remain flat to the Technician case.
4. Time to cut and drill.
   Start by cutting out bottom part of Technician case. I drilled 4 holes in the corners from the bottom and then cut along the edges with a Jig Saw.
5. Use drilling helpers to drill holes down into the notches in Box 130.
   There are two helpers (short and wide) for front notches and one (wide) for three on the rear. Arrow on the helpers should point outwards.
6. Remove original connector clips from Box 130.
7. Put nylock nuts only into notches part of front and rear prints.
8. Screw down front and rear prints to Box 130 via recently drilled holes. Use flat head 8mm screws.
9. Put Technican case on top of Box 130.
10. Connect both elements using two printed clips. Note that wider part goes upwards (towards Technician Case)
11. Drill horizontal holes through front/rear parts into a Technician case.
    I recommend holding the case from the inside while applying a bit of force from the top. Case at this step is very flimsy, thus it is easy to drill holes into a wrong spot that would mess with the alignment.
12. Put nylock nuts into all the remaining holes
13. Screw elements together from the inside.
    Rear part uses only 12mm button head screws.
    Front part uses two 12mm flat heads for the outer ones that go through a slanted edge. 4 holes in the middle use 12mm button heads like the rear ones.
     

That's it, you should be left with a assembled case :)

Final notes

You may notice that on my photos rear screws are slightly misaligned (literally 1mm to low and to the side). I fixed that in the models. Also the 1mm gap between rear parts is fixed.

A and B variants of front/rear models are just mirrored parts. So if you need to make any adjustments, just edit one and then do a mirror copy of adjusted one.
