3/4" to 1" Bench Dog Hole Adapter

thingiverse

My new workbench came pre-drilled with 1" dog holes that immediately rendered all my 3/4" size clamps, dogs, and stops obsolete. Of course, this is no problem if you have a 3D printer and can design a simple adapter that fits snug in the bench and has a 3/4" hole. My bench came with several 1" dogs that I can use when the work piece needs to rest directly against the dog. Therefore, these adapters are designed to work with holdfasts, clamps, cookies, and other accessories that do *not* provide a vertical holding surface. Hence, the lip at the top of the adapter is used only to keep the adapter from disappearing down the bench hole and not as a clamping surface. Several sizes are provided to accommodate different bench top thicknesses. If these don't suit your purpose you can edit the files directly on Tinkercad: https://www.tinkercad.com/things/4NNVvsCegjO (3rd parties can ungroup these to tune them, right? If not let me know and I'll leave them ungrouped.) When I printed these on a Prusa MK3s, PETG provided a perfect fit and PLA was a bit too snug, but still usable. Be sure to test-print the small one before committing to a large batch. UPDATE: A member asked for the objects in individual files so they can be farmed out to print services. I've uploaded each object in its own file to this thing. Please let me know if the print services can select the right file or if I need to upload them to individual things.
