PSA Two-Wide Portrait Slab Protector for Graded Card Shipping

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 PSA slabs with bubble wrap and tape, I began to look for a better solution since cutting the cardboard was tedious and pre-cut envelope stiffeners are not that sturdy.

This model fits graded collectible cards that are enclosed in two-wide portrait orientation PSA slabs. It was designed to fit naked slabs (no plastic sleeve around the PSA slab) and sleeved PSA slabs. It may be a little loose or a little tight depending on the sleeve you use and variations in the PSA slabs. This design was not intended for over-size items that PSA grades.

The slots in the design are to save filament and weight. The protector weighs 0.995 ounce / 28.1 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 carrier, PSA slab and a bubble wrap mailer will weigh ~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.

I calculated the average cost to print the holder was $0.48-$0.50 based on a PLA cost of $15 per kilo. Cost adds up but with a $50, $250, or $500 card it is better to not get a damaged card claim and loss of the total value of the card. Be sure to take pictures of the packaging and send to your client prior to sending off.

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:

Standard PSA Two-Wide Portrait slab measures used for the design are: 

    5.93 inches x 4.42 inches x 0.24 inches (our measurements)

    150.1 mm x 112.1 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.
