Ryanair 40x20x25 cm cabin bag sizer template
A collapsible frame that reproduces the Ryanair small personal bag limit of 40 x 20 x 25 cm, so you can check a backpack or tote at home before it is measured at the gate. Four corner posts and eight 20 mm square bars slot together into an open box with an exact 400 x 200 x 250 mm interior, each joint a 12 mm square peg with 0.3 mm clearance, and the bars print in 200 mm sections joined by printed M12 threads so the kit fits a 220 mm bed. Engraved marks on the posts show the easyJet 45 x 36 x 20 cm and Wizz Air limits too. Print the bars flat in PETG with 2 mm walls and 20 percent infill.

Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
