Tool Peg with a 2 degree angle, mounted with 2 screws.
I haven't really tested the strength of it, but it should be enough to mount a couple metric wrenches on it at once. peg is roughly 30 to 40 mm long.
Infill I used was around 50 to 70, so a single piece takes 45 to 75 min.
If you would like to, go ahead and revise, the gaps between each peg could probably 5 to 10mm shorter if you are tight on space.
Fit-wise side-to-side, there is a bit of play, design was given 1 mm of leeway between pieces. so it would easily fit.
Countersunk hole seems to fit a #6 or #8.
Novice at making these things, and this was made with Tinkercad.
If this happens to be similar to another persons creation. Sorry, wasn't on purpose.
The author marked this model as their own original creation.
