CONSTRUCTION & FIT
More open mesh. Less frame in the way.
We keep the frame as small as the design allows to maximize open mesh area, with light penetration and gas exchange in mind.
01 / CONSTRUCTION
Mesh you can see through.
FRAMEOPEN MESH
The frame is 3D printed in black PETG, with clear ¼-inch mesh embedded during printing. The main open area is mesh, rather than a solid acrylic panel.

02 / FIT

Illustrative side view · not to scale
The frame rests on glass. A drop-down edge sits inside the opening and limits sideways movement. Accurate measurements define that fit.

DETAILS BEFORE YOU DESIGN
Common questions, clearly answered.
How is my lid priced?
Your lid is priced at CA$0.30/cm³ of finished printed material, including supports and printed accessories. See your exact price in the builder before checkout. Shipping and taxes are calculated at checkout.
What do I need to measure?
Start with a saved tank profile when one is available, but treat it as a starting point. You confirm your tank's outside dimensions, equipment clearances, and production drawings before we manufacture.
Are Keepr lids flat underneath, and should I add clearance?
The lid top stays flat. The frame bears on the tank glass or eurobrace, and on exposed overflow walls inside the clear opening. Overflow walls underneath a eurobrace need no separate support; a locating edge extends below the overflow wall on the water side. Enter 0 for an overflow flush with the glass supporting the lid, or its measured distance below that surface. For eurobraced tanks, measure from the eurobrace top. Enter exact physical measurements without adding clearance; the builder applies the fit allowance.
Read the complete measurement guide.
What is the lid made from?
A mesh lid with a black PETG frame. Clear 1/4-inch mesh is secured in the frame during printing.
How does the Keepr Fit Guarantee work?
After you approve the production drawings, if the lid still does not fit the same tank, Keepr will remake it once at no charge. You pay remake shipping. Claims must be submitted within 30 days of delivery, and the total dimension change must be 2 inches or less.
How is standard order shipping calculated?
Standard order shipping is not included in printed-volume pricing. It is calculated separately at checkout based on the order and destination.
