the calliper is very accurate, it shoes take some concentration to see the fine lines. the pieces fit together perfectly and slide smoothly after applying grease. it would be very nice of you could make one with a least count of 0.1 cm as it would be easier to read. the print profile is also very nice as out printed very fast and without any issues. them you for such a good model

really good print. it is a good alternative for the ready made shelf pins which are very expansive. I used these as a door hinge in a project, it supported the weight very well. it only takes 1 gram which is very good. thank you for such a good print and design.
