thingiverse

A replacement paper roll guide for a SNBC BTP-M300 receipt printer (an impact printer sometimes distributed as part of Toast POS installations.) Quoting from the user manual: > There are three long slots at the bottom of paper cabinet. The > paper guide could be plugged in different slot which is suitable > for different wide paper, such as 76.5±0.5 mm, 69.5±0.5 mm, > 57.5±0.5 mm. If paper guide is not been used, the printer is > suitable for 80±0.5 mm paper width. For more information please see the BTP-M300 [user](https://www.snbc.com.cn/news/190.html) or [service](https://www.manualslib.com/manual/2387494/Snbc-Btp-M300.html) manuals, which are available elsewhere online :) This model varies from the depiction in the service manual, but has been tested in production with 76mm paper rolls and despite some slop in the guide width, print quality has been fine. Measurements to generate this model were taken on a single printer, from scratch, using paper models. Please let me know if you encounter any issues!
