Remix of the original Miter Box for X-Acto Saw (Parametric) by wsy.

This version fixes some missing formulation, placing automatically the reinforcement cylinders and slots, that now can be placed off-centered.

The sample SLT is provided with one 90º and two 45º slots, as I always do right angles.
Length 150mm
Width 20mm
height 15mm

You can personalize the overall dimensions and the placement, angle and size of the saw slots and reinforcements editing the parameters.
Just open the file in OpenSCAD and modify the commented variables as desired. It is surprisingly easy.

Tested in PLA and works brilliantly.

All credit should go to the original author (https://www.thingiverse.com/thing:473666), as I have only applied some trigonometry to allocate the non-automated dimensions. I have never worked in OpenSCAD before beyond changing variables in other people's projects, so this might need some polishing and is provided "as is".
Please contact me if something doesn't compute and I'll try to fix it.

Cheers.
Jose
