Work Box IKEA Samla (Dremel)

Ive got inspired by the Dremel box (https://www.thingiverse.com/thing:2836453) from @Wox. The design is good, but I wanted something a little bit diffrent, so I made it from scratch.
The diameter of the opening for the hands is 100mm and the bolts - M5. The hole in the box must me at least 106mm in diameter. The inner part is made for threading with a thread tap, but that can be changed in the Fusion 360 file or just use a drill and a M5 nut. The box wall thickness is calculated for 1,5mm.
Also if you have a box with flat walls you need only the Extern and Intern parts. But if you want to use IKEA Samla box you will need also tha adapter, while the wall is not flat. He can be used as a template for the holes. The adapter must be cut in two pieces and glued to the both Extern and Intern parts to compensate for the diffrence.
If the space between the two parts ot too big and the gloves slips away you can make a layer with a hot glue gun on the Intern part.

The STEP and Fusion360 files can be downloaded from this link.

EDIT v3: The holes are with correct size. Also there is already threaded part, ready for printing.
