I have a lot of Plarail tracks, and they take up a lot of space when stored in a case. I made this for storage to keep them tidy and prevent them from scattering. It's easy for a 3-year-old to store them like a puzzle, making tidying up convenient! In the photo, I made it to store 6 tracks. (There is a slight thickness error in the Plarail tracks, so one track is made with a thickness of 8.3mm) When not storing tracks, you can keep them together to avoid losing them, as shown in photos 9 and 10. Since the number of tracks you want to store may vary depending on the type, I can also create custom-made sizes based on the height or number of tracks you specify, so please comment ☘️ Basically, one set is 585 yen for the displayed size (holds up to 6 tracks). If it's a larger size, the price will be increased (+20 yen per track added). Please understand. You can get a discount with a bulk purchase! +1 set -50 yen +2 sets -100 yen +3 sets -150 yen … You can store not only curved tracks but also straight tracks(*´꒳`*) ■Size Length 38mm x Width 20mm x Height of storage part 50mm, Height of bottom base 3mm ■Material Polylactic acid (PLA) ■Color White ■Notes Although sanding is performed on some burrs in the final finish, please note that there will be some layer marks and burrs unique to 3D printers.
