(More Necks!) The Overheat Drum - The Stupidly Simple 50 Round Talon Drum Mag

Update Log

Update 5/9/26 - Added Nightengale, angled talon, and snail talon necks(required a small change in all neck connections), switched to 2 separate printed follower springs + a non-spring follower, and made the clock spring connection better. -5/10/26 - Also added 115mm long talon necks

Small Update 4/11/25 - Added an option for a follower lock key with a print-in-place key ring. Exciting update is coming soon…

Update 1/13/25 - Fixed a small generation error in the bottom text that caused a seam-like line to form. (Also rearranged folders)

Update 1/10/25 - (V2.2) Added option for text on the bottom, follower lock key to hold the follower in place while loading or not in use, and fixed the straight follower stopper yet again. (If you printed V2.1, just cut the little knobs on the back follower off, and it will work)

Update 1/8/25 - (V2.1)Changed the straight follower stopper to actually work🤦, made the neck connection stronger, and changed some tolerances. 

Update 12/29/24 - Made new followers that don't need screws.

Introducing the Stupidly Simple 50-Dart Talon Mag or the Overheat Drum! As the name suggests, this is a straightforward 50-dart drum magazine designed for Talon, angled, and Nightengale compatible magwells. It is mainly 3D printed and requires an M4 screw and nut, a 608 bearing, 5x 2mm thick pins, and a clock spring. Despite its high capacity, reloading is a breeze - simply undo the thumbscrew, then easily insert darts into the slots.

Instructions

It is now easier to make new mag necks! I have included a .step file of the neck base blank for you guys to put your favorite mag types on! Make sure to post it as a remix for others to use!

This model is still under development, so things may change and improve. I have a long list of improvements/additions that I still want to make.

Printing

All parts can fit on a printer with a printable area of 155mm x 155mm. PLA works great, but PETG is highly recommended for the printed follower springs. Print with normal settings, but add an extra perimeter or more infill. All parts are pre-oriented for printing. Supports should be enabled for the neck pieces(Enable "Don't support bridges" in your slicer).

(Make sure to measure from the top of your mag to the end of the magwell to make sure the mag fits. Longer necks will come soon.)

Assembly

Parts:

• 608 bearing

• 1x M4x20mm thumb or normal screw(You can 3D print a thumbscrew)

• 1x M4 nut

• 5x 2mm x 10mm metal pin

• 35mm x 6mm x 0.5mm Clock spring/Drill press return spring(This one works perfectly)

Full cost and BOM sheet here.

Main Follower:

• Start by placing the 608 bearing into the center hole of the Main Follower.

• Ensure it fits snugly and is fully pushed in.

• Place the 10mm pin into the hole on the Main Follower. (Super glue is suggested to hold the pin in)

Clock Spring Installation:

• Place the pin into the center of the outer end of the spring and flatten the end around the pin. Remove the pin from the spring.

• Cut the inner end of the spring to be shorter than 6mm and place that end into the slot on the Body Back. 

• Now, put the Main Follower into place, putting the pin into the outer end of the spring. (Some winding may be necessary) Make sure that the bearing fits tightly on the shaft, as that will help when loading.

Screw Installation:

• Place M4 nuts into the hex hole on the Body Back.

• Place 10mm-long pins in the 4 holes on the Body Back, and make sure they fit tightly.

• Make sure that the pins aren't very tight in the hole on the Body Front.

• Place your neck of choice in its respective slots at the top of the body pieces.

• Screw the Body pieces together with the M4x20mm thumbscrew in the middle.

Loading

Undo the screw and separate the body pieces. Fully wind the Main Follower back, then insert the Follower Lock Key into its slot and fill all but the innermost 3 segments with darts.

Next, place 2 follower springs into the 2 innermost sections of the body, and place the secondary follower that corresponds to your neck in the last empty segment.

Once you have done that, put the other Body part on and screw it back together. When you want to use the drum, take out the follower key, and you are ready to go.

If you are having trouble with the drum lagging behind, you can thinly apply silicon grease to the inside of the front half. It is also recommended to use worker-brand darts for the Nightengale neck, as the inner geometry is slightly smaller than mags made for normal 38mm darts.
