Maker Blade Pro is the next evolution of the 3D-printed utility knife designed specifically for makers. Built around a standard utility razor blade, it requires no extra hardware and delivers a large set of integrated tools for any 3D printing enthusiast:

• Triple-Position Blade Lock – locks safely closed, extends 5 mm for box opening, or fully extends for standard cutting.
• Filament Cutter – a flex-actuated feature that slices filament cleanly when the blade is closed.
• Tangle Finder & Cutter – trace tangled filament back to the knot with the built-in guide hole and snip it free on the spot.
• Filament Spool Gauge – precision-marked lines let you estimate how much filament is left on your spool in seconds.
  • Each ridge is an increment of 100g of filament, when you are at the base it starts at 1000g and moves towards the back of the blade until you hit the last ride which is 0g
• Replaceable Print Bed Scraper/Pry Tool – clips onto the back for removing prints; easily replaced when worn.
• Hidden PTFE Quick Disconnect – located under the scraper for fast tubing swaps on your printer or AMS setup.

Whether you’re opening boxes, managing filament, maintaining your printer, or swapping parts, Maker Blade Pro is a compact, customizable tool that earns a permanent spot on every maker’s bench.

Operation: The blade locks in multiple positions, closed, box opener (5mm), and fully extended. To get past the lock you must pull the thumb slide down towards the sharp edge of the blade and then move it forward and backward to your desired position.

Blade: Use a standard utility blade razor, the dimensions of mine are 61.5mm base X 32mm top X 18.95mm height

Materials: The outer handle of the blade can be printed out of any material, I chose PA6-GF for these pictures. Materials with additives like glass fiber or carbon fiber will be out of tolerance due to its additives so you can only use it for the outer materials. For the sliding blade holder on the inside as well as the bed scraper, use a basic filament without additives for the best experience, the more smooth the material the better. I have found that PLA Basic, PLA Silk+, PLA Metal, PETG HF, and ASA work the best.

Assembly:

This piece has an overlap which sticks together, gently push the pieces apart and it will click free

Pressing the cover over the ridge may take a lot of force the first time you do it. If it is giving you trouble, place it against the table and press the knife downward into it until it clicks into place
