Really cool and easy to assemble. I used -0.24 horizontal expansion in Cura to make sure everything fits :D

Modified the hinge by turning one of them 180 degrees. Broke the hinge with a plastic wrench I had. the 180 turn made it much easier.

Not sure if tree supports are the best here, but they worked ok.

Fun printable! Tips for printing would have been appreciated!

Such a cool model, really good job designing this.
Joints are sligtly challenging to print, but can be done.

tryTrying to make adjustments to the hinge but it doesnt download in .step format. this prevents me from importing into cad. ??

Very nice print. I also had problems with the pivots. I solved the issue by reducing the pivot rod from 6.7 mm to 6.65 mm and using a razor saw to open up the two pivots.

Easy print; nice work!

How can i go about converting the step files to STLs i cant open them in the step format in Cura.

All but the hinges were printed in PTGE, had to print the hinges in PLA to get them working.

But overall i love it.

Worked great, nice design

Just finished a *very* simple add-on for this. A post/stand for painting 28mm miniatures with.
