Surface Mount

Helps preserve the surface by mounting things using nuts and bolts instead of drilling holes and ruining walls with wood screws.

Can be embedded with a nut (and washer), reinforced using FRP.

Fully open-source and customizable, designed with ShapeScript.

Suggestions for nuts:

• https://sg.misumi-ec.com/vona2/detail/110302680850/ (composite)

Printing

Use strong filament material.  Depending on what you're planning to mount, try to make it as close to 100% infill as possible.

If you're embedding a nut (and washer), set a stop in the slicer right before the layer that puts the roof over the hardware chamber, insert the nut (and washer) in, then let printer finish the job.

Usage

After permanently attaching the surface mount, you can optionally reinforce it with composite matrix.  It can be done either with hand lamination or vacuum bagging.  In either case, the thread of the nut needs to be protected from resin, ideally by filling it with something water-soluble, that can be easily dissolved after the lamination process is complete and the resin is fully cured.
