parametric bed mounts for delta printer by randyrue

Last crawled date: 3 years, 1 month ago

Adaptable bed mounts for a round glass bed mounted on the beam base of a delta printer.
Enter the bed diameter, beam dimensions, measure the distance to the "completed triangle" of the frame base (details in the SCAD file comments).
Set the height of the retainer wall to accommodate the bed height i.e. plain glass or with insulator/heater/spreader/glass.
I've commented the SCAD pretty thoroughly so users can adapt as they need. Suggestions for improvements are welcome.
"Parametric_bed_mount" has a tab hanging under the bottom of the mount to make best use of print space height, but prints on its back edge and doesn't lend itself to a nice clean print.
"beam_top" version loses some print space height but prints flat really nicely, also has a much stronger support for the bed, especially if heated (I'd worry about the "tab" bending under a heated bed on the other version).
Both versions can be used with FSRs held under the bed with 3M double-sided adhesive tabs.
Included STLs are for a 240mm bed (pyrex disk came out of a silicone-sided cake pan) on a base of 270mm 15x15 OpenBeam extrusions, joined by Johann's laser cut aluminum corner brackets.
