Barbatronic uses Stenchill

Barbatronic is a French maker and robotics creator. On Twitch since 2019, he publishes hardware tutorials on YouTube, runs an active Discord community, and is a member of the Karibous team, which competes every year at the French Robotics Cup. A community of curious hackers and hands-on makers shows up each week for his practical hardware insights.

Stenchill was actually born in one of his streams. A chat discussion convinced me the idea was worth building and that I had the skills to ship it.

In this video, he integrates Stenchill into his fabrication workflow and shares his first impressions.

What is a stencil?

A stencil is a thin plate with openings matching the solder pads on your PCB. Place it on the board, spread solder paste with a squeegee, then position your SMD components before reflow. The result: precise and uniform paste deposits, much faster than using a syringe.

Designed for prototyping and small batches

3D-printed stencils work best with 0603+ passive components and large-pitch ICs. For finer components (0402, fine-pitch BGA), a laser-cut stencil is recommended. Use a 0.2mm nozzle for best results on small pads.

Why Stenchill?

• A professional stencil costs $15-30 per side, here it's free
• Generate your file in seconds, print it the same day
• Print it at home on your 3D printer
• Perfect for old PCBs: get a stencil after the fact, no need to reorder
• Built-in registration shoulders for perfect alignment

3D printing tips

Material

PLA or PETGPLA works great, PETG offers slightly more rigidity

Print bed

Smooth surfaceGlass, smooth PEI or mirror gives a flat face that spreads paste cleanly

Nozzle

0.2 mmRecommended for best results. A 0.4 mm nozzle is still acceptable

Layer height

0.1 mmEssential for a smooth surface and good paste application

Stencil thickness

0.3 - 0.4 mm3 to 4 layers at 0.1 mm. Thinner = less paste, thicker = more deposit

Infill

100%Full infill ensures stencil rigidity

Wall generator

ArachneVariable-width walls for narrow pad openings

Print speed

30 - 40 mm/sSlow speeds give cleaner pad edges and avoid skipped fine features
