Two-Wide Collectible Card in Top Loader Protector for Shipping & Mailing

I developed a series of collectible card protectors to protect the expensive cards that I was shipping out for sports cards and other collectible cards sold on eBay and through other sites. After cutting up cardboard and wrapping the cards with bubble wrap and tape, I began to look for a better solution to protect the cards since cutting the cardboard was tedious and pre-cut envelope stiffeners are expensive and not that sturdy..

This model fits non-graded two-wide portrait orientation folding collectible cards that are stored in sleeves and a two-wide top loader. It does not fit graded cards in slabs such as PSA or Beckett. It may be a little loose or a little tight depending on the top loader that you use and variations in these items. This design was not intended for over-size or extra thick cards. 

The slots in the design are to save filament and weight. The protector weighs 0.945 ounce / 26.8 grams We have found that the weight of the holder allows cards to be shipping within the standards of the shipping labels obtained through eBay. The card, top loader, protector and a bubble wrap mailer will weigh 2.5 to 3 ounces if using standard USPS or other mail services. 

Note: For more expensive cards we also user corrogated cardboard for even more protection of the valuable card. We have never had an issue with a card shipped with these protectors.

You may need to load the STL or model and adjust the length or width by a small about (0.01-0.03 inches / 0.25 - 0.55 mm). Do not adjust the height unless you are shipping a thicker slab, then adjust accordingly. We have had slabs 1.5x to 2.1x the standard slab thickness. Contact me if you something else.

I calculated the average cost to print the holder was $0.44 based on a PLA cost of $15 per kilo. 

I print these in PLA and have created models for Bambu and Prusa printers. I have a Bambu X1C and a Prusa XL, so minor adjustments may be needed for your printer.

Notes:

The two-wide top loader measures used for the design are: 

    5.91 inches x 4.21 inches x 0.235 inches (our measurements)

    150 mm x 107 mm x 6.05 mm (our measurements)

Settings

Filament:    PLA

Layer Height:  0.2 mm

Infill:   Grid or Gyroid (but likely does not matter due to thickness of print).

You may need to adjust depending on how true your printer is due to shrinkage.
