Wall mounted quick clamp holdes in two typs.

1. Max 38mm quick clamp teeth - 2 slot, if combined with the mirrored version 4 slot

2. Max 30mm quick clamp teeth - 3 slot, if combined with the mirrored version 6 slot

They are designed in 2 pieces that fit 2 OR 3 clamps each.
You don't have to print both, or mount them like i have done in the picture.
They are not meant to cross combine nicely 38mm with mirrored 30mm for example, however it is possible

But if you do want the 4/6 slot solution, print one of each file (the normal one and mirrored)

The screw holes are 5mm in diameter.

Filament
I recommend , PETG-CF, ABS (-GF) or ASA(-CF).
Personally i've printed it in Bambulab PETG HF. It works, but i do see that a stiffer material would have been better or something that withstands weight creep a little better than PETG.

Print Settings

1. Orientation like the picture.

2. Supports are optional, i personally prefer to use it.

3. Layer height 0.2mm

4. 4 Walls (Perimeters)

5. 1.2mm top and bottom layer

6. Gyroid or Cubic infill I recommend min 15-20% (What I used 15%)

I also have a generic model for Bahco quick clamps here:
