The Ultimate Modular Sprue Holder by FoxPaw-Prints!
This is a sprue holder that is capable of holding sprues/runners, sticker/transfer sheets of all sizes (thanks to the extending arm), and tools. It all folds away neatly and stacks so that when you are finished building you can put it away and it won't take up much space, it will also be able to store your tools while folded up which provides a convenient place for them between builds.
The parts all slide together and hold on well enough that a bump won't misallign them. They are also capable of stacking on top of eachother when folded.
There are alot of joints in this model so you will need to print it at a high accuracy to ensure stength. The bases for the main holder and sticker version will need printed with supports for the gap underneath as well as the arm for the sticker holder, the rest should print fine without any supports.
It works for all model kits, it is built for kits like Gunpla and Airfix vehicles.
-------To Assemble--------
Sprue Holder
Print 2 arms, 1 base and 4 pins. Position the arms to face eachother so the hinges overlap, then put 2 pins inbetween them. Place them in the base and put a pin through the hole in the base and the hole at the bottom of the top arm.
Sticker Holder
Print 1 sticker arm, 1 arm, 1 sticker base, 1 sticker plank and 4 pins. The process is the same for the sticker holder, just make sure the sticker arm faces downwards on the base. The sticker plank slides down through the top of the track in the sticker arm, the tolerences should make it so that the plank holds its position when you move it up and down.
