22mm Target Patch Dispenser

thingiverse

Patch dispenser designed for 22mm square patches provided by Pistol New Zealand (PNZ) for IPSC targets is available. It features a check window and roll directional guide. Print flat side down. Have printed once so far in PLA+, very strong and dispenses well. May 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 a bushing for the middle is added 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. A wider version is added to accommodate the new style patches. Lid remains the same, so simply re-print the body and bushing. Increased 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.
