22mm Target Patch Dispenser

thingiverse

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. U/W: https://www.pistolnz.org.nz/category/131417 Update: turns out the roll starts binding in the centre, 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 centre measurements, added some chamfering to reinforce walls and locking tabs.
