COMPAREE VERDICT

RCMakerLab built a scroll saw where almost every structural part is 3D-printed. The files are free on Printables, and the creator lists every bought part in the video description: a DC 775 24 V motor, 608 and 673ZZ bearings, LM8UU linear bearings, GT2 pulleys and belt, 8 mm steel rods, a 2 mm acrylic plate, a 24 V supply and a PWM speed controller. The licence forbids commercial use, so you cannot sell the saws. The creator publishes no total cost, so price the listed parts yourself before you start. The single biggest risk is substituting a different motor or pulley than the listed ones, because the printed mounts are sized for them. This is for someone comfortable with a long print queue, basic wiring and following an assembly video.

GOOD TO KNOW

  • —STL files and assembly photos provided on Printables.
  • —Full parts list with links is in the YouTube video description; extra details on the creator's site (rcpano.net).
  • —Licence is CC BY-NC-SA 4.0 — you cannot sell these or use them commercially.
  • —The 12-minute build video shows the assembly steps and the saw cutting.
  • —Motor, blade, bearings, fasteners and 24 V power supply must be sourced separately.
  • —Total cost not published by the creator.

BUILDS OF THE WEEK

Five open-source builds worth your weekend, every week.

Can I build this?

Printfull structural frame, motor mounts, blade guides, table — almost everything except metal hardware
Buy24 V motor, scroll saw blades, bearings, fasteners, 24 V power supply
Tools3D printer (some parts in PETG, ABS or ASA), screwdrivers, soldering iron for the XT60 connector and wiring, possibly a drill
Skillsfollowing an assembly video, intermediate 3D printing (PLA and PETG parts), basic 24 V wiring
Timea weekend once you have all the parts; longer if you have to order twice
Cost$$, dominated by the motor and power supply — but no published total, so budget cautiously
SafetyExposed moving blade: keep fingers out of the blade path and wear safety glasses, as the creator recommends. The saw itself runs on 24 V DC, but the power supply plugs into mains, so use a closed, properly rated supply and keep its mains terminals covered. Keep children away while it runs.

This build involves mains voltage — for adults comfortable with electrical work only.

Build at your own risk. Projects involve tools, electronics and sometimes mains voltage — follow the creator’s safety notes.

Start here

Navigation into the creator’s own docs — we don’t rewrite the guide, we route you to the source.

  1. 1.Download the STL files from Printables and study the assembly photos to identify required hardware (The parts list with links is in the description of the build video, not on Printables itself.)
  2. 2.Source a 24 V motor, scroll saw blades, bearings, and fasteners that match the printed mounts(Check motor shaft diameter and mounting hole spacing carefully before ordering.)
  3. 3.Print all parts, assemble, wire the 24 V supply, and test with scrap wood before attempting finished cuts(Keep fingers well clear during testing.)

KNOWN ISSUES

  • Substituting a motor other than the listed DC 775 24 V: the printed motor mount and pulleys are sized for it, so a different can size or shaft will not fit.
  • Underestimating print time: a full structural frame is many hours of filament.
  • Forgetting the licence is non-commercial: you cannot sell printed saws or the design files.
  • Assuming the blade will self-tension like a commercial saw — you may need to tune holder tightness by trial.
  • Skipping a test cut on scrap: check blade alignment and table angle on scrap wood before cutting anything you care about.

What motor do I need?

A DC 775 24 V motor, ideally around 3000 rpm (6000 rpm max). The creator lists it, together with the 24 V 5-6 A power supply, PWM speed controller, bearings, pulleys and belt, in the description of the build video.

Can I sell puzzles I cut on this?

The CC BY-NC-SA licence covers the saw's design files: you cannot sell printed saws or the files. The licence says nothing about the things you cut with it, so selling your own puzzles is a separate question from the saw's licence.

How much will it cost?

Not published. Budget for filament plus the listed parts: a DC 775 24 V motor, 24 V power supply, PWM speed controller, bearings, GT2 pulleys and belt, steel rods, acrylic plate, blades and fasteners.

Is this safe for kids to use?

No. It has an exposed moving blade, and the creator warns cutting tools can be dangerous and recommends safety glasses. The saw runs on 24 V, but its power supply plugs into mains. Adult operation only.

FROM THE COMPAREE TEAM

This saw cuts jigsaw puzzles clean enough that pieces drop out, and it runs on a common 775-size 24 V motor with a PWM speed controller. Would you print it, or does a desktop scroll saw only make sense as a bought tool?

CompareeTEAM6d agoedited

Practical notes from our verification: the Printables page has the STL files and assembly photos, and the full parts list sits in the description of the official YouTube video, with written details on rcpano.net. The roughly 12-minute video shows the assembly steps as well as the saw cutting a jigsaw puzzle cleanly enough that pieces drop out. The motor is specified: a DC 775 24 V motor, ideally run around 3000 rpm (6000 rpm max), fed by a 24 V 5-6 A power supply through a PWM speed controller. Match the shaft and mount to the printed parts before you order, because the wrong variant means reprinting or adapters. If you have a parts bin and patience for trial assembly, this is a genuine tool build you can finish from the published material. Correction (4 October 2026): we re-checked this page line by line against the project's own repository, documentation and videos, and fixed errors in earlier versions.
