I bought an IKEA Raskog cart and wanted to use the gridfintiy system to organize my stuff. But I didn't realize the cart comes in two different sizes and the available models are only for the bigger cart, so I designed a baseplate which fits into the smaller version (compartement size appr. 325x235 mm) of the cart inspired from the remixed models.

I designed a 7 x 5 baseplate using the GridfinityGenerator PlugIn for Fusion360 and edited the baseplate so it fits into the Raskog. It is split into half, so it's possible to print it on most beds (It just fits on the bed of my Ender 3 PRo) . I uploaded two versions, one with a cover that hides the short side of the tray with the screw. The cover has the height of an 8u bin. The other version is without this cover, which reduces printing time (So far I only have pictures of the version with cover, but the other one should also fit). 

I hope I have designed the sides with enough space to the edges of the tray, as the Raskogs sometimes have larger deviations in their tray size.

Edit: Since there were problems with the fit in the corners, I slightly increased the radius of the corner (37.5 mm vs. 35 mm). I left the old version in the v1 folder, so you can choose which one fits better. You will find the new versions with the rounder corners in the v2 folder.

Edit 2: Added a version with magnets (Size: 6x2 mm), but only for the version with the 37.5 mm corners. You find these models in the v2 folder. 

Disclaimer: Up to this moment, I did not print and test this version of the model!!!!
