Crane model based on Cranosaurus from Szczecin city.
It has moving parts and can hold notes with its hook (with second, small magnet).
UPDATE: Use 'new cranosaurus' files (plus Cranozaurus Magnet Move TILE - if needed).
Hole sizes are compensated for 0.4mm nozzle. Should work with most of printers. You may need a pliers to put 1.75mm filament in holes easier (there should be some resistant).
If the hole is too big then use old files (cranozaurus) and little drill
to make holes the rigth size.
new cranosaurus magnet.stl is with all parts together. You can print seperate parts too (parts numbers are on the graphic)
Yes, I know that it should be written with S instead of Z :P
Parts 1 and 2 can be glued together if you like.
There is a file '_tile' that can help with magnetic tape or too slim magnet.
Check your magnet thickness, if its smaller than 1,6mm then print '_tile' part (resize it on Z axis to size where tile and magnet combined will have 1,6-1,7mm and then glue the tile to part no.1.
Short video using magnet:
Simple, free version of crane:
21cm standing crane for assembling (>30 parts)
No supports needed.
Moving parts (no.3-5) should have 100% infill.
