Wanted a toolbox that faced forward. Was a little concerned the two corner screws weren't going to hold it, but they are plenty rigid. The holes are countersunk, but I only had barrel headed hex screws (M3x12) that worked fine too. I was also concerned that it would be in the way of my side mounted spool, but after mounting it, no issues.
15% infill, Rectilinear infill pattern, 0.20
The author remixed this model.
Front facing, for the K1 and not the K1 Max (though might work, don't have one so can't say)
