My first attempt at a parameterised model.
I need to connect a 20x20 (Bosch Rexroth) aluminium profile vertically to a flat 20x40 profile at 45 degrees. This model has tabs that will sit in the slots on the 20x40 profile.
The model has the following parameters:
attachAngle: Set the engle at which the vertical profile attaches to the horisontal profile.
Insert: Sets how far the tabs insert into the verticle profile.
Tabs: If false, tabs are left off to produce a flat end plate.
Hole: if false, leaves the hole for a flat end plate.
tol: set the tollerance for your printer.
OpenSCAD model included for further customisation
Update: I've measured the STL in Sketchup with calibrated models of my aluminium profile (Pictures added) to confirm that this should fit perfectly.
