The parent system is neat, but it contained no way to slot tools like try or machinist squares and digital angle rulers on wall control panels.

Additionally, I found some of the sidepiece flats and pins in the parent to have hooks that were too tight in the slots, and/or too loosely fitting with the centerpiece pins in a variety of different filaments, so I needed to alter some of the tolerances.

Using some of the STEP files provided in the parent remix, I carefully cycled through several test-print cycles until I got good fits for the parts I needed. Hopefully these STEP files help other people with fitment issues in the parent design.

Parts Included

• Left/right flats: Universal for all designs in this post. Adjusted hole size and hook thickness for better fittings (vs parent). STEP data for these is included in the AngleRulerHolder_AndFlats.STEP file.
• Angle Ruler Holder: A mount for common digital angle rulers, like this one sold here: https://www.amazon.com/General-Tools-822-Digital-Finder/dp/B00563TM32 . See picture of the mount in gallery.
• CombiSquareHolder: A mount for combi-squares. I sized mine to fit for the pair of craftsman ones I had (pictured). You might want a different slot hole size if you've got something smaller/bigger on yours.
• MachinistSquareHolder: A mount for a common machinist's square, as pictured.

Printing

I recommend printing the left/right flats presented here instead of the ones in the parent, as i've altered them not to catch on the wall-control panels, and i've also altered the pins and holes to fit better, particularly if you plan on super-gluing them together to form single solid parts.
