BED SLINGERS — DO IT BACK AND FORTH

For the 3D-printing enthusiast who likes their Y-axis moving aggressively and their humor operating at approximately middle-school level.

This heavyweight tee pays tribute to the noble bed slinger: the printer architecture that says, “Why move a lightweight toolhead when I can throw the entire print back and forth at increasingly questionable speeds?”

Wear it while tuning input shaping, chasing ringing, arguing with CoreXY owners, or staring nervously at a tall print as your build plate tries to launch it across the room.

Perfect for people who:

• Know exactly why “back and forth” is funny
• Have watched a 300 mm-tall print wobble like a drunk antenna
• Believe speed benchmarks are a perfectly normal thing to get emotionally invested in
• Have said “the bed mass isn’t that bad” with a straight face
• Secretly enjoy watching their printer shake the furniture
• Know that “bedslinger” is both a motion system and, apparently, a lifestyle

Heavy, soft, durable, and far more stable than the object currently being whipped around on your Y-axis.

Product features

• 100% ring-spun US cotton — softer than your TPU, significantly less annoying to print
• Heavyweight 6.1 oz fabric — because this shirt needs more mass than your moving bed
• Garment-dyed softness — broken-in feel without requiring 400 hours of calibration
• Tubular construction — no side seams, unlike the VFA lines you’re pretending not to see
• Double-needle stitching — stronger than the belt tension you definitely overdid
• Available S–4XL in 58 colors, which is somehow still fewer options than your slicer has
• Pre-shrunk, because unintended dimensional changes should stay in the printer

Care instructions

Machine wash cold.

Tumble dry low.

Do not bleach.

Do not dry clean.

Do not attempt to input-shape the washing machine.

And if the shirt starts moving back and forth at 20,000 mm/s², check your belt tension.
