Saberforge 28mm/1.1" RB 18650 Spear Chassis

This is a 28mm/1.10" x 154mm/6.06" chassis with removable battery provision for use specifically in SaberForge spears, nagamaki, naginata, lance, or whatever you wanna call it. It's specialised for lances because it  has  a flared 28mm upper end that sits near your switch section to prevent the chassis from sinking too low into your extension handle, but the majority of the chassis is 25mm/0.985" wide so that it DOES fit into the extension. It's also a long long man because I can't fit a Proffie or NB underneath a battery holder in a 25mm diameter. (Yet.)

Features specific to my chassis designs include, but are not limited to:

• Placement for a removable protected 18650! All other chassis in this size category use a fixed 18650, necessitating a recharge port. However, for long days trooping or training, charging up a battery from a port can take way too long. Being able to hot-swap batteries is the best solution, especially with high-drain setups that use Neopixel.
• FIts the single-board Proffieboard, dual-board Arduino Mini+TeensySaber, Plecter Labs Crystal Focus X and  Pico Crumble and Nano Biscotte v3/v4 + PEX, and 7Chambers CoreFX or JQSabers Spectra boards in a large 38mm x 19mm x open topped 12-16mm D-shaped area I guess
• Unique to this chassis: FINALLY COMPATIBLE WITH CRYSTAL SHARD V3/V4 IT'S FINALLY WIDE ENOUGH
• NOT COMPATIBLE WITH CRYSTAL FOCUS 9 OR BELOW, OR ANY NAIGON BOARDS  Please don't try and fit any of them in here. It won't work. If you do this and you blame me you're wrong.
• YES IT'S COMPATIBLE WITH CRYSTAL FOCUS X
• NOT COMPATIBLE WITH NANO BISCOTTE V4.1 why are you getting this if you have a 4.1
• Mounting ring with 12.5mm depth and two cutouts for any speaker of your choice with a 25mm maximum diameter, such as SaberEssentials 24mm! You may have to sand down the speaker cutouts a bit, but all aforementioned examples worked fine on the test mounting.
• Glue channels along the left and right sides of battery holder to hold stuff in.
• Wire channel underneath battery holder

You will need to purchase a Keystone 1042/1042P/1043 battery holder from an appropriate vendor, such as Digi-Key, Mouser, or TCSS ("18650 single cell holder" from them). Upon receiving the holder, you're going to have to cut off the plastic nubs sticking off the bottom. (A future revision may have mounting holes but don't hold your breath. I keep including this line in the copypasted versions. Really, don't stop breathing.) Before you finish your installation, you're going to have to glue it to the chassis in order to ensure a steady installation using the provided channels. High-temperature hot glue is my recommendation because it's a really strong space-filler, effectively acting as a thermoplastic.

In addition, your speaker is also going to need glue in the appropriate location/s. 24mm/25mm speakers will absolutely protrude from the end of the chassis, and will add anywhere from 3mm-5mm of overall length due to speaker vibration headspace.

If you're here, you probably already know that I make a different chassis with two variants.

• One of them is an 87mm long Saberforge removable battery chassis for NB+PEX,
• and the other one is the same but specialised for PRIZM and Proffie.

I'm sorry that this chassis is more expensive than the other two - it's extremely specialised and is more expensive to print. I hope you understand, though!
