How much should you charge for 3D printed plant drip & humidity trays?

Short answer for 2026: the market pays $12–30, a typical unit truly costs $10.79 to make and deliver, and at the $21 midpoint you keep $11.84 (46%) after Etsy's fees. Here is where those numbers come from.

The true cost of a typical unit (typical specs, estimated)

Assuming 60 g of PLA and 3.5 hours of printing, on a $399 printer at US electricity rates:

Material (incl. 5% waste)$1.26
Machine: wear + maintenance + power$0.54
Failed prints (8% rate)$0.16
Hands-on time$3.33
Packaging + postage$5.50
True cost per unit$10.79

At the market midpoint of $21 (buyer also pays $4.50 shipping), Etsy's stack takes $2.87, leaving $11.84 profit — a 46% margin and $3.38/printer-hour. Your floor is breakeven at $7.92; below that you are paying customers to take your prints.

Market reality

Saturation: low. Underserved by traditional manufacturers — only a handful of dedicated sellers.

Licensing: Simple original geometry; Etsy-compliant.
