Dog Hole Drilling Jig for MFT-Style Workbenches: A 3D Printed Guide for Cleaner Bench Layout and More Accurate 20 mm Hole Grids

3D printed dog hole drilling jig for MFT-style workbench layouts

Get this printed

Dog Hole drilling jig for MFT (Festool style) multi-function table on Printables stands out because it solves a bench-building accuracy problem instead of just adding another shop accessory. A lot of homemade dog-hole templates work fine for a few holes, then start losing trust as the drill rubs the printed plastic and introduces slop where the spacing matters most.

This design takes a stronger route. The source description explains that the printed jig is meant to hold a Lee Valley dog-hole drill bushing, so the bit rides against a real bushing rather than chewing up the template itself. That single detail gives the file a much better article angle than a thin “here is a jig” feature. It turns the conversation into layout accuracy, repeat drilling, wear resistance, and why hybrid shop tools often make more sense than all-plastic shortcuts.

That also makes it a believable outsourced-print candidate. Plenty of readers do not want to buy a printer just to build or upgrade one workbench top. But they may absolutely want a ready-made jig if it helps them lay out a cleaner 20 mm grid on an MFT-style bench, assembly table, or shop-made work surface without gambling on paper templates or imprecise eyeballing.

Direct source review showed about 319 downloads, roughly 3,310 visible views, 65 likes, 70 public collections, 2 makes, and 1 rating averaging about 5.00 on Printables. Those are solid numbers for a focused woodworking fixture, and the source description adds an unusually useful workflow note by explaining that the bushing protects accuracy over dozens or even hundreds of drilled holes.

If you are weighing whether a downloaded jig file is worth ordering, pair this with how to choose downloaded 3D models that are actually worth outsourcing, what to check on rights and permissions, and how to make sure a custom 3D printing quote covers the whole job before you approve it.

What problem this model solves

Bench dogs and 20 mm hole grids are only useful when the spacing stays controlled. If a drilling template wears quickly, shifts too easily, or lets the bit widen the guide path, the whole bench layout can drift from hole to hole. This model is useful because it treats the jig like a precision helper rather than a disposable plastic stencil.

  • helps lay out cleaner 20 mm dog-hole grids on MFT-style tops and shop-built benches
  • uses a drill-bushing approach so the bit is not constantly wearing the printed guide surfaces
  • supports repeat drilling where consistency matters across multiple rows or a larger bench panel
  • gives non-printer owners a sensible one-off outsource reason when they only need the jig for a bench build or upgrade

Why this design is worth noticing

The strongest idea here is durability through separation of jobs. The printed body handles alignment and positioning, while the bushing handles direct drill guidance. That is exactly the kind of hybrid workflow that makes a 3D printed shop aid feel legitimate instead of flimsy.

The source page also frames the problem clearly: many printed drill templates wear out fast and lose precision. That makes this article more useful than a generic spotlight because readers can learn not just that a jig exists, but why the wear path matters and what design choice makes this one more credible.

Who gets the most value from it

This file fits woodworkers building MFT-style work surfaces, cabinet and furniture makers who want cleaner workholding layouts, and serious DIY bench builders who would rather set up once and drill with more confidence than improvise off paper marks.

  • building a new MFT-style bench top
  • adding a hole grid to an assembly surface or outfeed table
  • repairing or replacing a worn top where hole spacing needs to stay trustworthy
  • upgrading from throwaway printed templates to a bushing-based guide path

How to use the idea even if you never order the file

The bigger lesson is that precision jigs wear where the tool touches them. If the drill bit itself is the wear surface, the template degrades. If the printed part only locates a hardened or purpose-built guide, the geometry lasts longer. That is useful bench-planning logic whether you print this exact file, buy a jig, or build your own hybrid guide system.

Readers can take away a much better question for future shop fixtures: which part should locate, and which part should take the wear?

Use notes

  • Check the bushing requirement: the source description specifically mentions Lee Valley dog-hole drill bushings, so confirm the exact hardware you plan to use before ordering or printing.
  • Match your bench system: this is aimed at MFT-style 20 mm hole-grid work, not every random bench layout.
  • Start from a known reference edge: even a good jig works best when the first row is located cleanly.
  • Think about repeatability, not just the first hole: the value here shows up more as the grid expands across a panel.

If you need help turning a downloaded file into a finished part, JC Print Farm is the broader service path for one-offs and small batches built from supplied models.

When ordering one makes sense

This model makes sense when you are building or upgrading a bench now and want a more trustworthy guide than paper templates or a full-plastic drill path. It is easy to understand, tied to a real woodworking task, and useful enough that ordering one finished jig can be cheaper in time and frustration than experimenting through a misaligned grid.

Ownership and print-offer note

The public Printables payload exposes `excludeCommercialUsage: false`, which is a positive signal, but this pass did not independently confirm the exact human-readable commercial-use wording on the live listing. Editorial coverage is clear, while production rights for the exact file should still be treated as unclear until the live source terms are confirmed directly.

Common questions

Why use a printed dog-hole jig instead of laying everything out by hand?

Because the whole point is repeatability. If you are building an MFT-style bench, one layout error can keep multiplying across the surface, while a guided jig helps hold spacing and alignment together from the first holes to the last.

Does the drill-bushing detail really matter?

Yes. The bushing takes wear that would otherwise chew up the printed guide, which helps the jig stay more accurate across a full bench build instead of getting sloppier as the project goes on.

Who is this file best for?

It fits woodworkers, cabinet builders, fixture makers, and serious DIY bench projects where cleaner 20 mm hole spacing matters more than improvising with one-off measurements.

What should you confirm before ordering this jig?

Confirm hole size, spacing standard, stock thickness, drill or bushing compatibility, and whether you want one guide or several for leapfrogging across a larger top. Those details matter more than the jig looking close enough in a screenshot.
