CardMod Frame · fits every standard 3 × 4 top loader
The display frame for top loaders that snaps into a wall.
Slide a top loader in from the top and the clear plastic becomes the glass. Every edge carries the same dovetail slot, so frames lock into rows, columns and whole walls with a slip-in key and no tools. Printed to order in matte black. From $14 a frame, with keys and caps included.

What you get
Each frame ships ready to connect
The frame
One piece, 84.4 × 105.7 × 11.4 mm, 20 g. Open top, interior groove for the top loader, 3 mm front lip, chamfered face. Open back so the card back shows too.
Two keys
A double dovetail, one for a horizontal joint and one for a vertical joint. Slide one into any joint between two frames and they are locked edge to edge.
Four caps
Flush fillers for any edge without a neighbour: two horizontal, two vertical. The frame's own chamfered corners finish the wall, so there is no corner piece to lose.
How it connects
Any frame joins any other, from any edge
There is no left or right version and no order to get wrong. Build the shape first, lock it second.
01
Load
Card into its top loader, top loader down into the frame until it sits flush with the top edge.
02
Lay out
Frames face down, edges touching, in the shape you want: a row over a desk, a 3 × 4 wall, an L around a shelf.
03
Key
Push a key into each joint line from the outside edge and slide it along to the joint. One key per pair of frames.
04
Cap
Slide a cap into every open edge. Turn it over. Square corners, flush edges, nothing showing but cards.
Frames touch face to face, so a wall's size is the frame count times 3.32 × 4.16 in. A 4 × 8 wall of 32 frames is 13.3 × 33.3 in and weighs about 1.5 lb.

Questions
Before you order
Which top loaders fit?
Any standard 3" × 4" top loader for 35pt cards: Ultra Pro regular, BCW, Cardboard Gold and the common equivalents, all 76.2 × 101.6 mm. Thick 130pt and 180pt top loaders and one-touch magnetic cases do not fit this frame. The top loader can hold a penny-sleeved card as it normally would.
How does the card go in?
Put the card in its top loader as usual, then slide the top loader down into the frame through the open top. An interior groove holds it on both sides and the bottom, and the front lip covers the edges by 3 mm. To take it out, tip the frame upside down or push the top loader up from behind through the open back.
How do frames connect to each other?
Every frame has the same dovetail slot along all four edges. To join two frames, lay them edge to edge and slide a key into the joint. Keys slide along any row or column from the outside of the assembly, so you can place every frame first and lock them afterwards, in any order. Caps slide into any edge left open and sit flush, so every finished wall has square corners.
Can I take a wall apart or change a card later?
Yes. Slide the keys back out and the frames separate. The top row loads and unloads in place; for a lower row, lift the row above by pulling its horizontal keys.
Do the frames hang on a wall?
This version is built for shelves, desks and easels, and holds its shape as a connected wall when leaned or set on a ledge. A hanging bracket that uses the same slot is next on our list.
What is it made of, and how is it finished?
PLA, printed in matte black at 0.2 mm layers with the front face against a textured build plate, which gives it an even matte finish with no sanding or paint. Each frame is about 20 g. PLA is stable indoors; keep it out of a hot car or direct summer sun.
How long until it ships?
Every order is printed when it is placed. Allow 1 to 3 business days before it ships. US orders travel 3 to 6 business days by USPS Ground Advantage; Canada 7 to 14 business days. Shipping is $5.95 in the US and free from $39; $12.95 to Canada and free from $99.
What if a key or cap is too tight?
Tolerances are set so keys and caps slide with thumb pressure and stay put. If a part is tight, run it along the slot a few times; PLA burnishes in. If one is wrong, reply to your order email and we print and ship a replacement at no charge.
