Mag Release Mod for Rival Caliburn U - Simplified

thingiverse

## NOTE: This thing contains only the modified mag release lever and magazine back piece. You will need to download the original Rival Caliburn U - Simplified by Captain Slug to get all the parts. You will also need a number of screws and other metal parts to complete this blaster. Captain Slug kindly sells kits with just the non-printable parts on his Etsy site! I had a couple issues with the original design. The two posts that hold the spring that holds down the "RTooth4" are a little thin. I found one of mine was broken when I finished printing all the parts for this blaster and finally took the ROGMagBack out of the box I was keeping all the parts in. Maybe I didn't do a good job printing the original part, but I beefed up the posts and they seem much stronger now. The other issue I ran into is the mag release (ROGmr2) didn't seem to hold my magazines in at all. I lowered the position of the tab that holds the magazine in, and it works great now. I changed the position of the hole in ROGMagBack for the pin that goes through the mag release. If you already have a Rival Caliburn U, and just want the new mag release without reprinting ROGMagBack and completely disassembling your blaster you could just drill a new hole. Look at the included ROGMagBack_ModV2 file for the new location. I printed the parts with 1.5mm 4 layer walls, 40% cubic infill, 0.2mm layer height, and I used eSun PLA+ Black. I just finished reassembling my blaster this morning and the new mag release works great. ### Thank you Captain Slug for the awesome blaster!! <s>He should really enable tips on his Thingiverse though, because I would love to give him more money! ;-)</s> Oh! Strike that, tips are enabled now. Tip sent! ## Last note, just to clarify what is different from the original: ROGMagBack_ModV2.stl replaces ROGmagback.stl ROGMagRelease_ModV1.stl replaces ROGmr2.stl
