22mm Target Patch Dispenser

[01/05/2022] UPDATE: All files migrated to Printables: https://www.printables.com/model/186753

Patch dispenser designed to accommodate 22mm square patches provided by Pistol New Zealand (PNZ) for IPSC targets. Features a check window and roll directional guide. Print flat side down.

Have printed once so far in PLA+, very strong and dispenses well. Might try it in PETG next.

Update: turns out the roll starts binding in the center, so I've added a bushing for the middle to prevent this. Also added an additional structural support pillar to the mouth to stop the lid from rotating slightly out of alignment.

Update 2: The most recent batch of patches has a wider ribbon (31mm), and won't fit the older design. I have added a wider version to accommodate the new style patches. Lid remains the same, so simply re-print the body and bushing. I have also increased the tolerance between the bushing and spindle by 1mm, and the top and bottom by 0.25mm as some people were having difficulties fitting them together.

Update 3: After a few more test prints fixed incorrect center measurements, added some chamfering to reinforce walls and locking tabs.
